Make controller-manager resilient to stale serviceaccount tokens
Now that the controller manager is spinning up controller loops using service accounts, we need to be more proactive in making sure the clients will actually work.
Future additional work:
* make a controller that reaps invalid service account tokens (c.f. https://github.com/kubernetes/kubernetes/issues/20165)
* allow updating the client held by a controller with a new token while the controller is running (c.f. https://github.com/kubernetes/kubernetes/issues/4672)

Adjust nodiskconflict support based on iscsi multipath.
With the multipath support is in place, to declare whether both iscsi disks are same, we need to only depend on IQN.

Convert HPA controller to support HPA v2 mechanics
This PR converts the HPA controller to support the mechanics from HPA v2.
The HPA controller continues to make use of the HPA v1 client, but utilizes
the conversion logic to work with autoscaling/v2alpha1 objects internally.
It is the follow-up PR to #36033 and part of kubernetes/features#117.
**Release note**:
```release-note

Improved code coverage for plugin/pkg/scheduler/algorithm/priorities…
…/most_requested.go
**What this PR does / why we need it**:
Part of #39559 , code coverage improved from 70+% to 80+%
There was a bug in the HPA v1 conversion logic that would occur when
a custom metric and a metric that was encoded in v1 as
targetCPUUtilizationPercentage were used at the same time. In this
case, the custom metric could overwrite the CPU metric, or vice versa.
This fixes that bug, and ensures that the fuzzer tests round-tripping
with multiple metrics.

route53 dnsprovider: add more logging

[Federation][e2e] Remove ns creation in federated clusters
**What this PR does / why we need it**:
In federation e2e, framework creates a namespace for each test case. the same ns is supposed to be created in federated clusters. Due to issues in namespace controller, this was not working earlier. but now it is working.
so currently the namespace is created twice, once by namespace controller and another when we call `getRegisteredClusters`. depending on the timing of these 2 calls, some [test cases fails ](https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/logs/ci-kubernetes-e2e-gce-federation/1199#k8sio-federation-secrets-featurefederation-secret-objects-should-not-be-deleted-from-underlying-clusters-when-orphandependents-is-true). So removing the creation of namespace when `getRegisteredClusters` which is unnecessary.

kubeadm: Make a separate util package for kubeconfig logic
**What this PR does / why we need it**:
There are a lot of packages that need to consume kubeconfig logic, so it should be in a central place.
Having it in `kubeadmutil` is suboptimal, because then it get mixed with everything else.
This splits that logic out to a generic place so it then also can be consumed in https://github.com/kubernetes/kubernetes/pull/41417, from where it's broken out.

Rotate the kubelet certificate when about to expire.
Changes the kubelet so it doesn't use the cert/key files directly for
starting the TLS server. Instead the TLS server reads the cert/key from
the new CertificateManager component, which is responsible for
requesting new certificates from the Certificate Signing Request API on
the API Server.

@liggitt and @ymqytw ptal, you were in the original issue
We have some heuristics that ensure that volumes (and hence stateful set
pods) are spread out across zones. Sadly they forgot to account for
multiple mounts. This PR updates the heuristic to ignore the mount name
when we see something that looks like a statefulset volume, thus
ensuring that multiple mounts end up in the same AZ.

This will allow us to pass e.g. a ResourceRecordChangeset, rather than a
ResourceRecordChangeset, the parent ResourceRecordSets, and the
grandparent Zone.
