* Add the tracing environment variables to the proxy spec
* Add tracing event
* Remove unnecessary CLI change
* Update log message
* Handle single segment service name
* Use default service account if not provided
The injector doesn't read the defaults from the values.yaml
* Remove references to conf.workload.ownerRef in log messages
This nested field isn't always set.

* 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.

Performing this check earlier helps to separate the specialized logic to the CLI
and webhook.
Any subsequent modification of this check logic to support config override of
existing meshed workload will be confined to the relevant component.
The shared lib can then focus only on config overrides.

Have the Webhook react to pod creation/update only
This was already working almost out-of-the-box, just had to:
- Change the webhook config so it watches pods instead of deployments
- Grant some extra ClusterRole permissions
- Add the piece that figures what's the OwnerReference and add the label
for it
- Manually inject service account mount paths
- Readd volumes tests

Fixes#2377
In inject's ResourceConfig, renamed objMeta to podMeta since
it really points to the pod template metadata. And created a new field
workloadMeta that really points to the main workload (e.g. Deployment) metadata.
Refactored uninject to clean up the labels at both podMeta and
workloadMeta. Also it will remove all the labels and annotations that
start with "linkerd.io" except for the "linkerd.io/inject" annotation.

- Created the pkg/inject package to hold the new injection shared lib.
- Extracted from `/cli/cmd/inject.go` and `/cli/cmd/inject_util.go`
the core methods doing the workload parsing and injection, and moved them into
`/pkg/inject/inject.go`. The CLI files should now deal only with
strictly CLI concerns, and applying the json patch returned by the new
lib.
- Proceeded analogously with `/cli/cmd/uninject.go` and
`/pkg/inject/uninject.go`.
- The `InjectReport` struct and helping methods were moved into
`/pkg/inject/report.go`
- Refactored webhook to use the new injection lib
- Removed linkerd-proxy-injector-sidecar-config ConfigMap
- Added the ability to add pod labels and annotations without having to
specify the already existing ones
Fixes#1748, #2289
