Allow shareable resources for admission control plugins.
Changes allow admission control plugins to share resources. This is done via new PluginInitialization structure. The structure can be extended for other resources, for now it is an shared informer for namespace plugins (NamespiceLifecycle, NamespaceAutoProvisioning, NamespaceExists).
If a plugins needs some kind of shared resource e.g. client, the client shall be added to PluginInitializer and Wants methods implemented to every plugin which will use it.

controller/service: minor cleanup
1. always handle short case first for if statement
2. do not capitalize error message
3. put the mutex before the fields it protects
4. prefer switch over if elseif.

use a separate queue for initial quota calculation
When the quota controller gets backed up on resyncs, it can take a long time to observe the first usage stats which are needed by the admission plugin. This creates a second queue to prioritize the initial calculation.

Fix "PVC Volume not detached if pod deleted via namespace deletion" issue
Fixes#29051: "PVC Volume not detached if pod deleted via namespace deletion"
This PR:
* Fixes a bug in `desired_state_of_the_world_populator.go` to check the value of `exists` returned by the `podInformer` so that it can delete pods even if the delete event is missed (or fails).
* Reduces the desired state of the world populators sleep period from 5 min to 1 min (reducing the amount of time a volume would remain attached if a volume delete event is missed or fails).

Allow mounts to run in parallel for non-attachable volumes
This PR:
* Fixes https://github.com/kubernetes/kubernetes/issues/28616
* Enables mount volume operations to run in parallel for non-attachable volume plugins.
* Enables unmount volume operations to run in parallel for all volume plugins.
* Renames `GoRoutineMap` to `GoroutineMap`, resolving a long outstanding request from @thockin: `"Goroutine" is a noun`
When a new rollout with a different size than the previous size of the
deployment is initiated then only the new replica set will notice the
new size. Old replica sets are not updated by the rollout path.
Allow mount volume operations to run in parallel for non-attachable
volume plugins.
Allow unmount volume operations to run in parallel for all volume
plugins.

Certificate signing controller for TLS bootstrap (alpha)
The controller handles generating and signing certificates when a CertificateSigningRequest has the "Approved" condition. Uses cfssl to support a wide set of possible keys and algorithms. Depends on PR #25562, only the last two commits are relevant to this PR.

Improve quota controller performance by eliminating unneeded list calls
Previously, when syncing quota usage, we asked each registered `Evaluator` to determine the usage it knows to track associated with a `GroupKind` even if that particular `GroupKind` had no associated resources under quota.
This fix makes it that when we sync a quota that just had only `Pod` related compute resources, we do not also calculate the usage stats for things like `ConfigMap`, `Secret`, etc. per quota.
This should be a significant performance gain when running large numbers of `Namespace`'s each with `ResourceQuota` that tracks a subset of resources.

[GarbageCollector] Let the RC manager set/remove ControllerRef
What's done:
* RC manager sets Controller Ref when creating new pods
* RC manager sets Controller Ref when adopting pods with matching labels but having no controller
* RC manager clears Controller Ref when pod labels change
* RC manager clears pods' Controller Ref when rc's selector changes
* RC manager stops adoption/creating/deleting pods when rc's DeletionTimestamp is set
* RC manager bumps up ObservedGeneration: The [original code](https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/replication/replication_controller_utils.go#L36) will do this.
* Integration tests:
* verifies that changing RC's selector or Pod's Labels triggers adoption/abandoning
* e2e tests (separated to #27151):
* verifies GC deletes the pods created by RC if DeleteOptions.OrphanDependents=false, and orphans the pods if DeleteOptions.OrphanDependents=true.
TODO:
- [x] we need to be able to select Pods that have a specific ControllerRef. Then each time we sync the RC, we will iterate through all the Pods that has a controllerRef pointing the RC, event if the labels of the Pod doesn't match the selector of RC anymore. This will prevent a Pod from stuck with a stale controllerRef, which could be caused by the race between abandoner (the goroutine that removes controllerRef) and worker the goroutine that add controllerRef to pods).
- [ ] use controllerRef instead of calling `getPodController`. This might be carried out by the control-plane team.
- [ ] according to the controllerRef proposal (#25256): "For debugging purposes we want to add an adoptionTime annotation prefixed with kubernetes.io/ which will keep the time of last controller ownership transfer." This might be carried out by the control-plane team.

[garbage collector] add e2e test
This PR also includes some changes to plumb controller-manager's `--enable_garbage_collector` from the environment variable.
The e2e test will not be run by the core suite because it's marked `[Feature:GarbageCollector]`.
The corresponding jenkins job configuration PR is https://github.com/kubernetes/test-infra/pull/132.
