1. Create controllerrevisions (history) and label pods with template
hash for both RollingUpdate and OnDelete update strategy
2. Clean up old, non-live history based on revisionHistoryLimit
3. Remove duplicate controllerrevisions (the ones with the same template)
and relabel their pods
4. Update RBAC to allow DaemonSet controller to manage
controllerrevisions
5. In DaemonSet controller unit tests, create new pods with hash labels

move labels to components which own the APIs
During the apimachinery split in 1.6, we accidentally moved several label APIs into apimachinery. They don't belong there, since the individual APIs are not general machinery concerns, but instead are the concern of particular components: most commonly the kubelet. This pull moves the labels into their owning components and out of API machinery.

@derekwaynecarr since most of these are related to the kubelet

Added a new test case for daemoncontroller.
This patch added a new test case of daemonSet with node selector,
matching some nodes, and launch pods on all the nodes.

Local storage plugin
**What this PR does / why we need it**:
Volume plugin implementation for local persistent volumes. Scheduler predicate will direct already-bound PVCs to the node that the local PV is at. PVC binding still happens independently.

Part of #43640
**Release note**:
```
Alpha feature: Local volume plugin allows local directories to be created and consumed as a Persistent Volume. These volumes have node affinity and pods will only be scheduled to the node that the volume is at.

Node status updater now deletes the node entry in attach updates...
… when node is missing in NodeInformer cache.
- Added RemoveNodeFromAttachUpdates as part of node status updater operations.
**What this PR does / why we need it**: Fixes issue of unnecessary node status updates when node is deleted.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#42438
**Special notes for your reviewer**: Unit tested added, but a more comprehensive test involving the attach detach controller requires certain testing functionality that is currently absent, and will require larger effort. Will be added at a later time.
There is an edge case caused by the following steps:
1) A node is deleted and restarted. The node exists, but is not yet recognized by Kubernetes.
2) A pod requiring a volume attach with nodeName specifically set to this node.
This would make the pod stuck in ContainerCreating state. This is low-pri since it's a specific edge case that can be avoided.

```release-note
NONE

GC: update required verbs for deletable resources, allow list of ignored resources to be customized
The garbage collector controller currently needs to list, watch, get,
patch, update, and delete resources. Update the criteria for
deletable resources to reflect this.
Also allow the list of resources the garbage collector controller should
ignore to be customizable, so downstream integrators can add their own
resources to the list, if necessary.
