d86d1defa1 Made IPVS and iptables modes of kube-proxy fully randomize masquerading if possible 
Work around Linux kernel bug that sometimes causes multiple flows to
get mapped to the same IP:PORT and consequently some suffer packet
drops.

Also made the same update in kubelet.

Also added cross-pointers between the two bodies of code, in comments.

Some day we should eliminate the duplicate code.  But today is not
that day.

edbb0fa2fe Add support for konnectivity service to the etcd3 client. 
If konnectivity service is enabled, the etcd client will now use it.
This did require moving a few methods to break circular dependencies.

935c23f2ad Move HostUtil to pkg/volume/util/hostutil 
This patch moves the HostUtil functionality from the util/mount package
to the volume/util/hostutil package.

All `*NewHostUtil*` calls are changed to return concrete types instead
of interfaces.

All callers are changed to use the `*NewHostUtil*` methods instead of
directly instantiating the concrete types.

5ed80dadcf Update CanAdmitPodResult() in TopologyManager to take a TopologyHint 
Previously it only took a bool, which limited the logic it could perform
to determine if a pod should be admitted or not based on the merged hint
from the policy.

c02d49d775 Update running_pod_count and running_container_count metric 
As already mentioned in this issue https://github.com/kubernetes/kubernetes/issues/79286, some metrics like
"running_pod_count" and "running_container_count" uses non-standard prometheus metrics, this change converts them to be
standard prometheus gauges

Minor refactor in kubelet/pleg/generic.go and added some test for ruuning container and running pod metrics

Fixed issues related to github CI pipeline failure

* Updated bazel for new deps
* Add comment for exported metrics variables,RuuningContainerCount and RunningPodCount
* Specify keys explicitly in Guage metric instantation

Fix go lint errors

Replace "+=1" with "++", as reported by go lint

Set container state as a label for the metrics "running_container_count"

As per the metrics name "running_container_count" it should "ideally" be showing
the number of containers in "running" state , but it was showing all the container count, irrespective of the state it is in.
This commit adds a new label "container_running_state" to the metrics "running_container_count", which doesn't change the base metrics but adds the
option to query the metrics with "container_state" such as "running"/"unknown/...

remove unused methods reported by staticcheck

Remove variables while instantiating gauge(vec) which are default set to nil

Convert kubelet metrics(running_pod_count and running_container_count) to standard gauges and added label to running_container_count metrics.

Currently kubelet metrics(running_pod_count and running_container_count) use non-standard prometheus collectors , this change
converts them to standard prometheus gauges. Also this adds a new label(container_state) to running_container_count which does a breakdown of
containers tracked by kubelet based on the containers' state(running/unknown/created/exited).

Set statbility explicitly for running_pod_count and running_container_count and reformat test

register metrics explicitly in test , so that they don't become no-op
