Create fake /etc/hosts for conformance test
**What this PR does / why we need it**:
"KubeletManagedEtcHosts should test kubelet managed /etc/hosts file"
conformance test fails in the CI's Docker-In-Docker environment.
This test mounts a /etc/hosts file and checks if "# Kubernetes-managed
hosts file." string is present or not under various conditions. The
specific failure with DIND happens when the /etc/hosts picked up
from the box where e2e test are running already has this string. This
happens because our CI runs on kubernetes and the e2e tests are running
in a container that was started on kubernetes (and hence already has
that string)
To avoid this situation, we create a new /etc/hosts file with known
contents (and does not have the "# Kubernetes-managed hosts file."
string)

Add support for binaries to run as Windows services

Add support for binaries to run as Windows services
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes#59562
**Special notes for your reviewer**:
**Release note**:
```release-note
kubelet and kube-proxy can now be ran as Windows services
```
When a newly started kubelet finds a directory where a volume should be,
it can be fairly confident that the volume was mounted by previous kubelet
and therefore the volume must have been in node.status.volumesInUse.
Therefore we can mark reconstructed volumes as already reported so
subsequent reconcile() can fix the directory and put the mounted volume
into actual state of world.
Previously, when `GetObjectMetricReplicas` calculated the desired
replica count, it multiplied the usage ratio by the current number of replicas.
This method caused over-scaling when there were pods that were not ready
for a long period of time. For example, if there were pods A, B, and C,
and only pod A was ready, and the usage ratio was 500%, we would
previously specify 15 pods as the desired replicas (even though really
only one pod was handling the load).
After this change, we now multiple the usage
ratio by the number of ready pods for `GetObjectMetricReplicas`.
In the example above, we'd only desire 5 replica pods.
This change gives `GetObjectMetricReplicas` the same behavior as the
other replica calculator methods. Only `GetExternalMetricReplicas` and
`GetExternalPerPodMetricRepliacs` still allow unready pods to impact the
number of desired replicas. I will fix this issue in the following
commit.

Pass in etcd TLS credentials during migrate and rollback
For HA etcd clusters, the `etcd-creds` settings, specifically the `--peer-*` TLS flags that may be included, must be passed in to `start-stop-etcd.sh` in order for the etcd server mode started during migrate and rollback steps to be able to communicate between peers.
The `etcd.manifest` change needs to be backported all the way back to 1.7.

This patch adds support for kubernetes to integrate
with Windows SCM.
As a first step both `kubelet` and `kube-proxy` can be registered as a service.
To create the service:
PS > sc.exe create <component_name> binPath= "<path_to_binary> --service <other_args>"
CMD > sc create <component_name> binPath= "<path_to_binary> --service <other_args>"
Please note that if the arguments contain spaces, it must be escaped.
Example:
PS > sc.exe create kubelet binPath= "C:\kubelet.exe --service --hostname-override 'minion' <other_args>"
CMD > sc create kubelet binPath= "C:\kubelet.exe --service --hostname-override 'minion' <other_args>"
Example to start the service:
PS > Start-Service kubelet; Start-Service kube-proxy
CMD > net start kubelet && net start kube-proxy
Example to stop the service:
PS > Stop-Service kubelet (-Force); Stop-Service kube-proxy (-Force)
CMD > net stop kubelet && net stop kube-proxy
Example to query the service:
PS > Get-Service kubelet; Get-Service kube-proxy;
CMD > sc.exe queryex kubelet && sc qc kubelet && sc.exe queryex kube-proxy && sc.exe qc kube-proxy

Local cluster is leaking memory due to mutation detector being enabled.
In addition there is no warning in the logs that this could be the
issue.
Added a log warning when this feature is enabled to make debugging this
issue easier for other cases of this.
