Add a label which prevents a node from being added to a cloud load balancer
There are a variety of reasons that you may not want a node in a cluster to participate in a cloud load balancer. For example workload isolation for security, or managing network throughput, or because the node is not in the appropriate virtual network (cluster's that span environments)
This PR adds a label so that you can select which nodes you want to participate.

Fix incorrect status msg in podautoscaler
**Which issue this PR fixes**
Fix#49256
**What this PR does / why we need it**:
When `ScalingLimited = true` for the `hpa`, there is an accompanying
status message, describing why scaling is limited. Previously if the desired
replica count was 0, and spec.minReplicas > 0, the status message
indicated "the desired replica count was less than the min replica
count". This was particularly confusing when `spec.MinReplicas = 1`. If
there was no `spec.minReplicas`, then the status message indicated "the
desired replica count was zero" which is more informative.
Update the calculation of status message so that if the desired replica
count is 0, we always display the clearer "the desired replica count was
zero" status message, even if spec.minReplicas > 0.

Eliminate hangs/throttling of node heartbeat
Fixes https://github.com/kubernetes/kubernetes/issues/48638Fixes#50304
Stops kubelet from wedging when updating node status if unable to establish tcp connection.
Notes that this only affects the node status loop. The pod sync loop would still hang until the dead TCP connections timed out, so more work is needed to keep the sync loop responsive in the face of network issues, but this change lets existing pods coast without the node controller trying to evict them
```release-note
kubelet to master communication when doing node status updates now has a timeout to prevent indefinite hangs

Ignore pods for quota marked for deletion whose node is unreachable
**What this PR does / why we need it**:
Traditionally, we charge to quota all pods that are in a non-terminal phase. We have a user report that noted the behavior change in kube 1.5 for the node controller to no longer force delete pods whose nodes have been lost. Instead, the pod is marked for deletion, and the reason is updated to state that the node is unreachable. The user expected the quota to be released. If the user was at their quota limit, their application may not be able to create a new replica given the current behavior. As a result, this PR ignores pods marked for deletion that have exceeded their grace period.

to where they belong and we check for PVLabeler method and use it where
needed.

If the previous condition has been a successful rollout then we
shouldn't try to estimate any progress. Scenario:
* progressDeadlineSeconds is smaller than the difference between
now and the time the last rollout finished in the past.
* the creation of a new ReplicaSet triggers a resync of the
Deployment prior to the cached copy of the Deployment getting
updated with the status.condition that indicates the creation
of the new ReplicaSet.
The Deployment will be resynced and eventually its Progressing
condition will catch up with the state of the world.

In some cases, the backoff delay for a given Job is reset unnecessarily.

- Centralize the key "forget" and "re-queue" process in only on method.
- Change the signature of the syncJob method in order to return the

key.
