Improve dynamic kubelet config e2e node test and fix bugs
Rather than just changing the config once to see if dynamic kubelet
config at-least-sort-of-works, this extends the test to check that the
Kubelet reports the expected Node condition and the expected configuration
values after several possible state transitions.
Additionally, this adds a stress test that changes the configuration 100
times. It is possible for resource leaks across Kubelet restarts to
eventually prevent the Kubelet from restarting. For example, this test
revealed that cAdvisor's leaking journalctl processes (see:
https://github.com/google/cadvisor/issues/1725) could break dynamic
kubelet config. This test will help reveal these problems earlier.
This commit also makes better use of const strings and fixes a few bugs
that the new testing turned up.
Related issue: #50217
I had been sitting on this until the cAdvisor fix merged in #51751, as these tests fail without that fix.

kubeadm: Perform TLS Bootstrapping in kubeadm join for v1.7 kubelets
**What this PR does / why we need it**:
Partially reverts 9dc3a661d7
Performs the TLS Bootstrap if `kubeadm join` v1.8 is executed on a node with a kubelet v1.7.
Since the kubelet arguments for v1.7 (from the kubeadm dropin) expects a TLS bootstrapped kubeconfig, we still have to provide this functionality in kubeadm CLI v1.8 (as we support one minor version down)

Allow watch cache to be disabled per type
Currently setting watch cache size for a given resource does not disable
the watch cache. This commit adds a new `default-watch-cache-size` flag
to map to the existing field, and refactors how watch cache sizes are
calculated to bring all of the code into one place. It also adds debug
logging to startup to allow us to verify watch cache enablement in
production.
Part of #51825
Will allow watch cache to be disabled selectively.

ScaleIO - Specify SDC GUID value via node label
**What this PR does / why we need it**:
This is a ScaleIO plugin volume PR to do the following:
- Reads node label `scaleio.sdcGuid` value for the SDC GUID
- Uses value to look up the Scaleio SDC `instance ID`
- If label not found, falls back to current way of doing instance id look up now
This enhancement allows the ScaleIO plugin to work properly even if the drv_cfg binary is not installed on the kubelet node.
**Special Notes**
Associated issue - #51537Closes#51537
```release-note
The ScaleIO volume plugin can now read the SDC GUID value as node label scaleio.sdcGuid; if binary drv_cfg is not installed, the plugin will still work properly; if node label not found, it defaults to drv_cfg if installed.
```
We should be able to build a cloud-controller-manager without having to
pull in code specific to GCE and AWS clouds. Note that this is a tactical
fix for now, we should have allow PVLabeler to be passed into the
PersistentVolumeController, maybe come up with better interfaces etc. Since
it is too late to do all that for 1.8, we just move cloud specific code
to where they belong and we check for PVLabeler method and use it where
needed.
Fixes#51629

Fix deployment timeout reporting
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.
Fixes https://github.com/kubernetes/kubernetes/issues/49637
I will also cherry-pick this back to 1.7.

apiservers: stratify versioned informer construction
The versioned share informer factory has been part of the GenericApiServer config,
but its construction depended on other fields of that config (e.g. the loopback
client config). Hence, the order of changes to the config mattered.
This PR stratifies this by moving the SharedInformerFactory from the generic Config
to the CompleteConfig struct. Hence, it is only filled during completion when it is
guaranteed that the loopback client config is set.
While doing this, the CompletedConfig construction is made more type-safe again,
i.e. the use of SkipCompletion() is considereably reduced. This is archieved by
splitting the derived apiserver Configs into the GenericConfig and the ExtraConfig
part. Then the completion is structural again because CompleteConfig is again
of the same structure: generic CompletedConfig and local completed ExtraConfig.
Fixes#50661.
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.

Bugfix: Improve how JobController use queue for backoff
**What this PR does / why we need it**:
In some cases, the backoff delay for a given Job is reset unnecessarily.
the PR improves how JobController uses queue for backoff:
- Centralize the key "forget" and "re-queue" process in only on method.
- Change the signature of the syncJob method in order to return the
information if it is necessary to forget the backoff delay for a given
key.

Disable default paging in list watches
For 1.8 this will be off by default. In 1.9 it will be on by default.
Add tests and rename some fields to use the `chunking` terminology.
Note that the pager may be used for other things besides chunking.
Follow on to #48921, we left the field on to get some exercise in the normal code paths, but needs to be disabled for 1.8.
