Add whitespace to improve error msg clarity
**What this PR does / why we need it**:
Currently when `kubectl explain` is called without a resource the error message is tacked onto the end of the list of valid resources. The error is clearer if there is a new line after the valid resource list, this also causes the error to be left aligned instead of indented level with the valid resource list.

On AttachDetachController node status update, do not retry when node …
…doesn't exist but keep the node entry in cache.
**What this PR does / why we need it**: An alternative fix for https://github.com/kubernetes/kubernetes/issues/42438 which also fixes#50721.
Instead of removing the node entry entirely from the node status update cache (which prevents the node from ever being updated even when it recovers), here the node status updater does nothing, so that there won't be an update retry until the node is re-added, where the cache entry is set to true.
Will cherry pick to prior versions after this is merged.

A pod status change of unready -> ready results in a move from
the endpoint's unready endpoint addresses to its ready addresses
so if a pod update contains an unready -> ready status change,
the endpoint needs to be updated.
The subfeature was a cool idea, but in the end it is very complex to
separate Kubelet restarts into crash-loops caused by config vs.
crash-loops caused by other phenomena, like admin-triggered node restarts,
kernel panics, and and process babysitter behavior. Dynamic kubelet config
will be better off without the potential for false positives here.
Removing this subfeature also simplifies dynamic configuration by
reducing persistent state:
- we no longer need to track bad config in a file
- we no longer need to track kubelet startups in a file

fix#51043
**What this PR does / why we need it**: The StatefulSet controller no longer attempts to mutate "hostname" or "subdomain" fields of the "pod.spec" to enforce the network identity of Pods in a StatefeulSet. Since these fields are set upon creation and immutable thereafter setting the annotations is no longer necessary.

Create the directory for cadvisor if needed
**What this PR does / why we need it**:
In 6c7245d464, code was added to
bail out if the directory that cadvisor monitored did not exist.
However, this breaks the earlier assumption that kubelet created
directories when needed in pkg/kubelet/kubelet.go's setupDataDirs()
method. setupDataDirs() happens much later, so basically kubelet
exits now.
So since cadvisor really needs this directory, let us just create
it

Revert "Merge pull request #51008 from kubernetes/revert-50789-fix-scheme"
I'm spinning up a cluster right now to test this fix, but I'm pretty sure this was the problem.
There doesn't seem to be a way to confirm from logs, because AFAICT the logs from the hollow kubelet containers are not collected as part of the kubemark test.
**What this PR does / why we need it**:
This reverts commit f4afdecef8, reversing
changes made to e633a1604f.
This also fixes a bug where Kubemark was still using the core api scheme
to manipulate the Kubelet's types, which was the cause of the initial
revert.

teach gce cloud to handle alpha/beta operations v2
Alternative to #50704
This one feels cleaner. BUT, type assertion problems cannot be exposed at compile time.
Please let me know what you think. This will set the precedence for consuming GCE alpha/beta API.
