If pet was evicted by kubelet - it will stuck in this state forever.
By analogy to regular pod we need to re-create pet so that it will
be re-scheduled to another node, so in order to re-create pet
and preserve consitent naming we will delete it in petset controller
and create after that.

add names for workqueues to gather controller latency/depth metrics
Adding names to the workqueues used by controllers allows the automatic collection of depth, rate, and latency metrics for those controllers. These are useful for diagnosing various "slow controller" cases.

Currently when processing an item in the dirtyQueue, the garbage collector issues GET to check if any of its owners exist. If the owner is a replication controller with 1000 pods, the garbage collector sends a GET for the RC 1000 times. This PR caches the owner's UID if it does not exist according to the API server. This cuts 1/3 of the garbage collection time of the density test in the gce-500 and gce-scale, where the QPS is the bottleneck.
1. When overlapping deployments are discovered, annotate them
2. Expose those overlapping annotations as warnings in kubectl describe
3. Only respect the earliest updated one (skip syncing all other overlapping deployments)
4. Use indexer instead of store for deployment lister

Add Cluster field in ObjectMeta
There will be no sub-rs, but add `Cluster` field to the ObjectMeta (for all the objects)
"To distinguish the object at the federation level from it's constituents at the cluster level we will add a "Cluster" field to the metadata of all objects (where the federation itself will also have a cluster identifier). That way it is possible to list, interact with, and distinguish between the objects either at the federation level or at the individual cluster level based on the cluster identifier. "

Avoid failure message flush log when node no longer exist
When node is deleted, attach-detach controller cache may contain stale
information of this node, and update node status fails in reconciler
loop. This message easily flush the log file. This PR is just a quick
fix of this issue. More complete fix including make controller cache
up to date will be addressed in another PR.

Node controller deletePod return true if there are pods pending deletion
Fixes https://github.com/kubernetes/kubernetes/issues/30536
If a node had a single pod in terminating state, and that node no longer reported healthy, the pod was never deleted by the node controller because it believed there were no pods remaining.
