golangci-lint disables some checks for golint, including checks for
well-formed comments on all exported symbols
This change disables the golangci-lint's `exclude-use-default` setting,
to run golint with default settings.
Also introduce a `.golangci.yml` file to centralize config.

`golangci-lint` performs numerous checks on Go code, including golint,
ineffassign, govet, and gofmt.
This change modifies `bin/lint` to use `golangci-lint`, and replaces
usage of golint and govet.
Also perform a one-time gofmt cleanup:
- `gofmt -s -w controller/`
- `gofmt -s -w pkg/`

# 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.
No change was required to successfully run `bin/go-run cli install`. No change
was required to run `bin/linkerd install`.
Fixes#2153

* Support auto sidecar-injection
1. Add proxy-injector deployment spec to cli/install/template.go
2. Inject the Linkerd CA bundle into the MutatingWebhookConfiguration
during the webhook's start-up process.
3. Add a new handler to the CA controller to create a new secret for the
webhook when a new MutatingWebhookConfiguration is created.
4. Declare a config map to store the proxy and proxy-init container
specs used during the auto-inject process.
5. Ignore namespace and pods that are labeled with
linkerd.io/auto-inject: disabled or linkerd.io/auto-inject: completed
6. Add new flag to `linkerd install` to enable/disable proxy
auto-injection
Proposed implementation for #561.
* Resolve missing packages errors
* Move the auto-inject label to the pod level
* PR review items
* Move proxy-injector to its own deployment
* Ignore pods that already have proxy injected
This ensures the webhook doesn't error out due to proxy that are injected using the command
* PR review items on creating/updating the MWC on-start
* Replace API calls to ConfigMap with file reads
* Fixed post-rebase broken tests
* Don't mutate the auto-inject label
Since we started using healhcheck.HasExistingSidecars() to ensure pods with
existing proxies aren't mutated, we don't need to use the auto-inject label as
an indicator.
This resolves a bug which happens with the kubectl run command where the deployment
is also assigned the auto-inject label. The mutation causes the pod auto-inject
label to not match the deployment label, causing kubectl run to fail.
* Tidy up unit tests
* Include proxy resource requests in sidecar config map
* Fixes to broken YAML in CLI install config
The ignore inbound and outbound ports are changed to string type to
avoid broken YAML caused by the string conversion in the uint slice.
Also, parameterized the proxy bind timeout option in template.go.
Renamed the sidecar config map to
'linkerd-proxy-injector-webhook-config'.

* Link to Grafana from Conduit Dashboard
Previously the only way to access the Grafana dashboards was via direct
link, provided by the `conduit dashboard` command.
Add Grafana links throughout the Conduit Dashboard, next to all
Deployment objects. This change also modifies the behavior of the
ConduitLink helper, to enable linking to other deployments proxied by
the `conduit dashboard` command.

We’ve built Conduit from the ground up to be the fastest, lightest,
simplest, and most secure service mesh in the world. It features an
incredibly fast and safe data plane written in Rust, a simple yet
powerful control plane written in Go, and a design that’s focused on
performance, security, and usability. Most importantly, Conduit
incorporates the many lessons we’ve learned from over 18 months of
production service mesh experience with Linkerd.
This repository contains a few tightly-related components:
- `proxy` -- an HTTP/2 proxy written in Rust;
- `controller` -- a control plane written in Go with gRPC;
- `web` -- a UI written in React, served by Go.
