CustomResourceDefinition parsing and retrieval is not available via
client-go's `kubernetes.Interface`, but rather via a separate
`k8s.io/apiextensions-apiserver` package.
Introduce support for CustomResourceDefintion object parsing and
retrieval. This change facilitates retrieval of CRDs from the k8s API
server, and also provides CRD resources as mock objects.
Also introduce a `NewFakeAPI` constructor, deprecating
`NewFakeClientSets`. Callers need no longer be concerned with discreet
clientsets (for k8s resources vs. CRDs vs. (eventually)
ServiceProfiles), and can instead use the unified `KubernetesAPI`.

Makes the "overview" view of the Linkerd dashboard functional on mobile devices, with responsive tables and a minimized sidebar.
Also lines up the sidebar icons and makes them a uniform size on both desktop and mobile views.
This is a first step towards a fully-responsive dashboard.
The UUID implementation we use to generate install IDs is technically
not random enough for secure uses, which ours is not. To prevent
security scanners like SNYK from flagging this false-positive, let's
just switch to the other UUID implementation (Already in our

Todo in a follow-up PRs: remove the SP check from the CLI check.

Problem:
In #2532 I removed the Tap/Top tables if there was no http traffic, but the
check I used depended on a stats object being present in the processed metrics
(spoiler: it isn't present in the processed metrics).
Solution:
Use a better check for no traffic.
The new check checks for both no requests (so nil request rate) and
also no latency (in the case that the service is http but receiving no traffic).

Adds local and cloud integration testing for the dashboard using WebdriverIO and
SauceLabs. Includes documentation on how to set up and run the Sauce Connect
proxy locally. Adds a `bin/web integration` script that takes `local` or `cloud`
arguments to run the tests.
Note: for web development, the web server launched by `bin/web run` and `bin/web
dev` is now 7777, not 8084, because the Sauce Connect proxy can only tunnel to
certain ports.

When installing Linkerd, a user may override default settings, or may
explicitly configure defaults. Consider install options like `--ha
--controller-replicas=4` -- the `--ha` flag sets a new default value for
the controller-replicas, and then we override it.
When we later upgrade this cluster, how can we know how to configure the
cluster?
We could store EnableHA and ControllerReplicas configurations in the
config, but what if, in a later upgrade, the default value changes? How
can we know whether the user specified an override or just used the
default?
To solve this, we add an `Install` message into a new config.
This message includes (at least) the CLI flags used to invoke
install.
upgrade does not specify defaults for install/proxy-options fields and,
instead, uses the persisted install flags to populate default values,
before applying overrides from the upgrade invocation.
This change breaks the protobuf compatibility by altering the
`installation_uuid` field introduced in 9c442f6885.
Because this change was not yet released (even in an edge release), we
feel that it is safe to break.

When a resource only has TCP traffic and no HTTP traffic, the dashboard looks
weird in a bunch of places.
This branch:
- updates the main resource card in the Octopus graph to show TCP stats if no HTTP
stats are available
- cleans up the resource detail page to show fewer blank
tables if the resource only has TCP traffic.
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.
Also remove single namespace integration test

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.

In #2195 we introduced `linkerd endpoints` on the CLI. I would like similar
information to be on the web.
This PR adds an api endpoint at `/api/endpoints`, and introduces a new debugging
pagethat shows a table of endpoints, available at `/debug`
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).
