This change introduces a new Identity service implementation for the
`io.linkerd.proxy.identity.Identity` gRPC service.
The `pkg/identity` contains a core, abstract implementation of the service
(generic over both the CA and (Kubernetes) Validator interfaces).
`controller/identity` includes a concrete implementation that uses the
Kubernetes TokenReview API to validate serviceaccount tokens when
issuing certificates.
This change does **NOT** alter installation or runtime to include the
identity service. This will be included in a follow-up.
The proxy's TLS implementation has changed to use a new _Identity_ controller.
In preparation for this, the `--tls=optional` CLI flag has been removed
from install and inject; and the `ca` controller has been deleted. Metrics
and UI treatments for TLS have **not** been removed, as they will continue to
be valuable for the new Identity system.
With the removal of the old identity scheme, the Destination service's proxy
ID field is now set with an opaque string (e.g. `ns:emojivoto`) to enable
locality awareness.
Fixes#2420.

Previously, running a Top query for a namespace and resource that did not return
data would permanently disable the 'start query' button even if a user chose a
new namespace/resource combination. This allows the user to perform a new query
after their previous query does not return data.

This PR creates a "Community" menu item on the dashboard sidebar that, when clicked, displays an iFrame of a page on linkerd.io. A yellow badge appears on the menu item if there has been an update since the user last clicked the "Community" menu item. This is calculated by comparing a date in the user's localStorage to a JSON feed at linkerd.io.
linkerd/linkerd2#1721 introduced a `--single-namespace` install flag,
enabling the control-plane to function within a single namespace. With
the introduction of ServiceProfiles, and upcoming identity changes, this
single namespace mode of operation is becoming less viable.
This change removes the `--single-namespace` install flag, and all
underlying support. The control-plane must have cluster-wide access to
operate.
A few related changes:
- Remove `--single-namespace` from `linkerd check`, this motivates
combining some check categories, as we can always assume cluster-wide
requirements.
- Simplify the `k8s.ResourceAuthz` API, as callers no longer need to
make a decision based on cluster-wide vs. namespace-wide access.
Components either have access, or they error out.
- Modify the web dashboard to always assume ServiceProfiles are enabled.

Some time ago, I fixed sorting on these tables so that the default route ([default])
was sorted to the bottom. The name was changed to [DEFAULT] causing that sort
to no longer put the default route at the bottom. Update to correct case.
linkerd/linkerd2#2428 modified SelfSubjectAccessReview behavior to no
longer paper-over failed ServiceProfile checks, assuming that
ServiceProfiles will be required going forward. There was a lingering
ServiceProfile check in the web's startup that started failing due to
this change, as the web component does not have (and should not need)
ServiceProfile access. The check was originally implemented to inform
the web component whether to expect "single namespace" mode or
ServiceProfile support.
Modify the web's initialization to always expect ServiceProfile support.

This PR adds filter functionality to the web UI via an optional Material-UI <Toolbar> on the top of the table which contains the table's title and a filter icon. The toolbar only shows if the enableFilter={true} prop is passed down from the parent component. The PR modifies the MetricsTable test and adds tests for BaseTable and TopRoutesTable.
Note: The previous Ant-based UI allowed certain tables to be filtered by individual table column; this capacity is not part of this PR but can be added later if useful.
The control-plane components relied on a `--single-namespace` param,
passed from `linkerd install` into each individual component, to
determine which namespaces they were authorized to access, and whether
to support ServiceProfiles. This command-line flag was redundant given
the authorization rules encoded in the parent `linkerd install` output,
via [Cluster]Role[Binding]s.
Modify the control-plane components to query Kubernetes at startup to
determine which namespaces they are authorized to access, and whether
ServiceProfile support is available. This allows removal of the
`--single-namespace` flag on the components.
Also update `bin/test-cleanup` to cleanup the ServiceProfile CRD.

This PR adds an api endpoint at `/api/endpoints`, and introduces a new debugging

Up until now, the proxy-api controller service has been the sole service
that the proxy communicates with, implementing the majoriry of the API
defined in the `linkerd2-proxy-api` repo. But this is about to change:
linkerd/linkerd2-proxy-api#25 introduces a new Identity service; and
this service must be served outside of the existing proxy-api service
in the linkerd-controller deployment (so that it may run under a
distinct service account).
With this change, the "proxy-api" name becomes less descriptive. It's no
longer "the service that serves the API for the proxy," it's "the
service that serves the Destination API to the proxy." Therefore, it
seems best to bite the bullet and rename this to be the "destination"
service (i.e. because it only serves the
`io.linkerd.proxy.destination.Destination` service).

When Kubernetes periodically pinged booksapp to perform a health check, the
lack of namespace violated the `TapLink` component's propTypes requirement.
This triggered a warning in the browser console when on the web UI Top view.

moved the check for an empty namespace to the top of the component to avoid an
unnecessary queryString construction.

The Linkerd logo on the top left of the web UI is now wrapped in a

@rmars and I set out to replace all instances of lodash filter with native
filter in order to prevent the additional import. However, there was only one
use of _filter that could be easily replaced, since our other uses depend on
lodash's ability to handle empty variables, and the ability to filter both
objects and arrays (JS's native filter is only for arrays). Switching to native
filter in those cases would have required us to manually check the value of the
variable, set it to an empty array and/or convert it from an object to an array.

When looking up service profiles, Linkerd always looks for the service profile objects in the Linkerd control namespace. This is limiting because service owners who wish to create service profiles may not have write access to the Linkerd control namespace.
Instead, we have the control plane look for the service profile in both the client namespace (as read from the proxy's `proxy_id` field from the GetProfiles request and from the service's namespace. If a service profile exists in both namespaces, the client namespace takes priority. In this way, clients may override the behavior dictated by the service.

# Problem
In order to switch Linkerd template rendering to use `.yaml` files, static
assets must be bundled in the Go binary for use by `linkerd install`.
# Solution
The solution should not affect the local development process of building and
testing.
[vfsgen](https://github.com/shurcooL/vfsgen) generates Go code that statically
implements the provided `http.FileSystem`. Paired with `go generate` and Go
[build tags](https://golang.org/pkg/go/build/), we can continue to use the
template files on disk when developing with no change required.
In `!prod` Go builds, the `cli/static/templates.go` file provides a
`http.FileSystem` to the local templates. In `prod` Go builds, `go generate
./cli` generates `cli/static/generated_templates.gogen.go` that statically
provides the template files.
When built with `-tags prod`, the executable will be built with the staticlly
generated file instead of the local files.
# Validation
The binaries were compiled locally with `bin/docker-build`. The binaries were
then tested with `bin/test-run (pwd)/target/cli/darwin/linkerd`. All tests
passed.

# Problem
In order to refactor `install` to allow for a more flexible configuration, we
should start with the format of the YAML that it renders. Using the Helm
YAML format will make it easier add flexible configuration options in the
future. Currently, the rendered template that `install` produces does not
follow this format.
# Solution
Use the internals that Helm itself uses to render an inject template that
follows the same formatting rules. Helm's `template` cmd provides a good
outline of what is needed to make Linkerd's `install` cmd work as if it was
a Chart.
# Validation
There are no new tests, but there may not be anything to test at this stage.
This is a WIP PR towards the ultimate goal of `install` allowing a more
flexible configuration.
However, `install` now uses all the Helm `template` internals and therefore
satisfies the needed properties for Helm Charts.

[web UI] Previously, we were specifying the display order to display the cli flags in the
QueryToCliCmd module. But this order is pretty standard for each command, and
I'd like to avoid hardcoding that list everywhere.
Move the handling of order into the QueryToCliCmd module.
Adds an endpoint, at /profiles/new that allows you to input a service name and
namespace, and download a service profile yaml template.
This will enable future work, where we can add more of the yaml customization via
a form in the dashboard, and use that data to help the user configure routes.
This change alters the controller's Tap service to include route labels
when translating tap events, modifies the public API to include route
metadata in responses, and modifies the tap CLI command to include
rt_ labels in tap output (when -o wide is used).
Previously, we were passing in "tap" as the command name for both the tap and
top forms, resulting in the equivalent CLI command always being linkerd tap
regardless of whether you were in the Tap or Top view.
Fix this to correctly pass in tap or top depending on the page.

Separates out the querying and table display of route data, so that this module

Adds usability improvements to the routes query form at /routes:
- displays CLI equivalent
- adds dropdown with populated options for service / namespace
As part of this work, made TapQueryCliCmd more generic, so it can work
for other CLI commands besides tap/top.
Adds a (currently not displayed in sidebar, but available at /routes) page to

barebones form and table, but it works.
Adds a /api/routes path and handler to the api to receive TopRoutes requests from the web.
Add a barebones ListServices endpoint, in support of autocomplete for services.
As we develop service profiles, this endpoint could probably be used to describe
more aspects of services (like, if there were some way to check whether a
service profile was enabled or not).
Accessible from the web UI via http://localhost:8084/api/services
Add a routes command which displays per-route stats for services that have service profiles defined.
This change has three parts:
* A new public-api RPC called `TopRoutes` which serves per-route stat data about a service
* An implementation of TopRoutes in the public-api service. This implementation reads per-route data from Prometheus. This is very similar to how the StatSummaries RPC and much of the code was able to be refactored and shared.
* A new CLI command called `routes` which displays the per-route data in a tabular or json format. This is very similar to the `stat` command and much of the code was able to be refactored and shared.
Note that as of the currently targeted proxy version, only outbound route stats are supported so the `--from` flag must be included in order to see data. This restriction will be lifted in an upcoming change once we add support for inbound route stats as well.
