Add more logging around Pod deletion
After this PR we'll have at least V(2) level log near all Pod deletions.
@saad-ali - this is required by GKE to help with diagnosing possible problem.

Check sysfs Type instead of Device
Some distribution uses "none" device to mount "sysfs" type, so kube-proxy needs to list mount points and check "types" instead of "device".
fixes#37183
```release-note
Change sysfs mountpoint tests from Device to Type to be able to find sysfs mountpoint on "none" device

Test flake: ignore dig failure; wait until timeout
The intent of this test was to continue trying until the timeout has
been reached. The extra assertion makes the test fail early when it
should not.

Update the timeout in CLOSE_WAIT e2e test
I see some test flakes due to the timeout being too strict,
updating to a larger value.
Adding tail -n 1, it looks like there may be leftover state for other
runs. We really only care about one of the CLOSE_WAIT entries.

Revert "Avoid hard-coding list of Node Conditions"
* we don't know how other API consumers are using node conditions (there was no prior expectation that the scheduler would block on custom conditions)
* not all conditions map directly to schedulability (e.g. `MemoryPressure`/`DiskPressure`)
* not all conditions use True to mean "unschedulable" (e.g. `Ready`)
This reverts commit 511b2ecaa8 to avoid breaking existing API users and to avoid constraining future uses of the node conditions API

Read all resources for finalization and gc, not just preferred
Fixes#31481.
Currently when starting namespace controller or garbage collector we only gather preferred version resources, which in case of multiple versions (you guessed it `batch/v2alpha1.CronJobs` again) isn't sufficient. This PR adds additional method which actually retrieves all resources from all versions and works on them.

[Federation][join-flags] Add flags for cluster context and secret names while joining clusters to federation.
Vast majority of cluster contexts are not RFC 1123 subdomains. Since
cluster and secret names for the API objects are derived from the
cluster context name, there is no way for users to join clusters
with such context names to federation, unless they modify the context
name in their kubeconfigs itself. That's a lot of inconvenience and
entirely goes against the goal and beats the purpose of the `kubefed`
tool. So we are providing these flags to allow users to override these
values.
Also, since users register their clusters with federation, it is makes
sense in terms of user experience to make the cluster name a positional
argument because that feels more natural. Also, specifying cluster name
in the join command as a mandatory positional argument make
`kubefed join` consistent with `kubefed unjoin`. This also means
`--cluster-context` is now made a flag and defaults to cluster name if
unspecified.
`--secret-name` also defaults to the cluster name if unspecified.
Fixes: Issue #35954

Validate pet set scale up/down order
This change implements test cases to validate that:
- scale up will be done in order
- scale down in reverse order

Filter out non-RestartAlways mirror pod in restart test.
Fixes#37202.
> A quick fix is to filter out non-RestartAlways pods. Because either RestartNever and RestartOnFailure pods could succeed, and we can not deal with terminated mirror pods very well now.

Fields with omitempty tag should still be considered as optional
We've added an "+optional" tag while ago for optional fields. Before that OpenAPI spec generated assumed all fields with "omitempty" in their json tags are optional. This should be still the case (as well as +optional tag) until these two things happen:
- We update all documentation asking developers to use +optional (My bad, I should have added this after the +optional PR)
- We fix swagger 1.2 spec generator to use +optional instead of omitempty.

Add kube-proxy logs to fluentd configs

Makes fluentd collect logs from kube-proxy. It's completely backward-compatible change that does not cause problems currently, so I suggest not to bump version.

Make desired objects in fed controller reconcilation function fully writable
When creating desired objects for sub-cluster in reconciliate functions we don't make full copies. This may result in unexpected race condition in the future when someone actually adds some object modifications (not needed in most cases but anyway - the cost of extra copy will be relatively small comparing to inter-cluster traffic). In case of ReplicaSet and Deployment the spec copy was a shallow one - ok for setting just replicas but also error-prone in the future.

We should always log something when control plane force deletes the Pod.
