Ivan Sim 4fba6aca0a Proxy init and sidecar containers auto-injection (#1714)
* 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'.

Rename `ca-bundle-distributor` to `ca`. (#1340)
`ca-bundle-distributor` described the original role of the program but
`ca` ("Certificate Authority") better describes its current role.
