When cni is set to kubenet, kubelet should hold the host port socket,
so that other application in this node could not listen/bind this port
any more. However, the sockets are closed accidentally, because
kubelet forget to reconcile the protocol format before comparing.
The input variable of function ConstructVolumeSpec is the volume spec
name instead of persistent disk ID. Previously the function directly
construct new volume spec by assigning volume spec name to persistent
disk ID, which will result in mismatching of mount path. The fix will
find the pdID according to mount path and construct volume spec with the
correct pdID.
The grace-period is automatically set to 1 unless --force is provided,
and the client waits until the object is deleted.
This preserves backwards compatibility with 1.4 and earlier. It does not
handle scenarios where the object is deleted and a new object is created
with the same name.
trusted storage pool from which persistent gluster volume
has to be provided.
This patch introduce a new storage class parameter which allows
the admin to specify storage pool/cluster if required.

kubelet: eviction: add memcg threshold notifier to improve eviction responsiveness
This PR adds the ability for the eviction code to get immediate notification from the kernel when the available memory in the root cgroup falls below a user defined threshold, controlled by setting the `memory.available` siginal with the `--eviction-hard` flag.
This PR by itself, doesn't change anything as the frequency at which new stats can be obtained is currently controlled by the cadvisor housekeeping interval. That being the case, the call to `synchronize()` by the notification loop will very likely get stale stats and not act any more quickly than it does now.
However, whenever cadvisor does get on-demand stat gathering ability, this will improve eviction responsiveness by getting async notification of the root cgroup memory state rather than relying on polling cadvisor.

**Special notes for your reviewer**:
**Release note**:
``` release-note
Fixed wrong service sessionAffinity stickiness time from 180 sec to 180 minutes in proxy mode iptables.
```
Since there is no test for the sessionAffinity feature at the moment I wanted to create one but I don't know how.

Add more logging around Pod deletion
After this PR we'll have at least V(2) level log near all Pod deletions.

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.

Revert "Use Gid when provisioning Gluster Volumes."
On further inspection the design in #35460 was not secure enough. This PR reverts the change.
This reverts commit 7a0d219d12.
