* Re-add the destination container to the controller spec
This fix is necessary to avoid data plane downtime during an upgrade to
stable-2.6. All existing older proxies will continue to send requests to
this destination container, until the data plane is restarted.
On restart, the new pods will start forwarding their requests to the new
linkerd-dst service.
* Use the 2.6 destination service fqdn
* Fixed unit tests
* Fix integration test failure

When running linkerd in HA mode, a cluster can be broken by bringing down the proxy-injector.
Add a label to MWC namespace selctor that skips any namespace.

* Couple of injection events fixes
When generating events in quick succession against the same target, client-go issues a PATCH request instead of a POST, so we need the extra RBAC permission.
Also we have an informer on pods, so we also need the "watch" permission
for them, whose omission was causing an error entry in the logs.

* Have the proxy-injector emit events upon injection/skipping injection
Fixes#3253
Have the proxy-injector emit an event whenever a injection happens, or
when injection is skipped for some reason (also added that reason into
the proxy-injector logs). The level is associated to the parent workload
(it can't be associated to the pod because at this point the pod hasn't
been persisted).
The event recorder was setup at the `webhook/server.go` level and passed
to the proxy-injector's `Inject` function. The sp-validator thus also
has access to the event recorder, but for now it's not using it.
Related changes:
- Refactored `api.GetOwnerKindAndName()` to have it return a more
generic object.
- Refactored `report.Injectable()` to also have it return the reason why
a workload is not injectable.
