**What this PR does / why we need it**:
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.

Fix splitProviderID for Azure
**What this PR does / why we need it**:
#46940 add 'splitProviderID' for Azure to get node name from provider, but it captures the resource id instead of node name.
Functions such as NodeAddresses are accepting node names:
84d9778f22/pkg/cloudprovider/providers/azure/azure_instances.go (L32)
With current implementation, it takes in a resource ID, and will result in following error
```

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.

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.
```

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.

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.

GCE: Bubble IP reservation error to the user when the address is specified.
This PR improves the debug-ability of internal load balancers when an IP fails to be reserved. I'm mostly worried about the case when the subnetwork URL is wrong or referencing a shared network from another project which isn't yet supported. As you can see from line 160, I had originally planned to surface the reservation error, but printed the wrong error.

do not update init containers status if terminated
fixes#29972#41580
This fixes an issue where, if a completed init container is removed while the pod or subsequent init containers are still running, the status for that init container will be reset to `Waiting` with `PodInitializing`.
This can manifest in a number of ways.
If the init container is removed why the main pod containers are running, the status will be reset with no functional problem but the status will be reported incorrectly in `kubectl get pod` for example
If the init container is removed why a subsequent init container is running, the init container will be **re-executed** leading to all manner of badness.

Fix setNodeAddress when a node IP and a cloud provider are set
**What this PR does / why we need it**:
When a node IP is set and a cloud provider returns the same address with
several types, only the first address was accepted. With the changes made
in PR #45201, the vSphere cloud provider returned the ExternalIP first,
which led to a node without any InternalIP.
The behaviour is modified to return all the address types for the
specified node IP.
**Which issue this PR fixes**: fixes#48760
**Special notes for your reviewer**:
* I'm not a golang expert, is it possible to mock `kubelet.validateNodeIP()` to avoid the need of real host interface addresses in the test ?
* It would be great to have it backported for a next 1.6.8 release.

Enable CRI-O stats from cAdvisor
**What this PR does / why we need it**:
cAdvisor may support multiple container runtimes (docker, rkt, cri-o, systemd, etc.)
As long as the kubelet continues to run cAdvisor, runtimes with native cAdvisor support may not want to run multiple monitoring agents to avoid performance regression in production. Pending kubelet running a more light-weight monitoring solution, this PR allows remote runtimes to have their stats pulled from cAdvisor when cAdvisor is registered stats provider by introspection of the runtime endpoint.

Charges quota only for initialized objects
Partially fix https://github.com/kubernetes/kubernetes/issues/51842.
Based on https://github.com/kubernetes/kubernetes/pull/51733/files. Only the commit "Don't charge quota when creating/updating an uninitialized object" is new.
The old plan was to charge quota for each update of uninitialized object. This PR makes the quota admission only charges the update that removes the last pending initializer. Because
* https://github.com/kubernetes/kubernetes/pull/51247, which lets sharedInformer see uninitialized objects, is not making the code freeze deadline. Hence, the quota replenishing controller won't capture deletion of uninitialized objects. We will leak quota if we charge quota for uninitialized objects.
* @lavalamp @erictune pointed out calculating/reserving quota is expensive, we should avoid doing it for every initializer update.
* My original argument was that quota admission should fail early so that user can easily figure out which initializer causes the quota outage. @lavalamp @erictune convinced me that user could easily figure the culprit if they watch the initialization process.
