Azure - Use cloud environment to instantiate storage client
**What this PR does / why we need it**:
Since 1.7 and managed disk for azure, blob storage on Azure cloud other than the default public one is broken, because kubernetes expect blob ressources URI to end with `.blob.core.windows.net ` (ignoring storageEndpointSuffix).
This include the chinese Cloud, for which storageEndpointSuffix is `blob.core.chinacloudapi.cn` for example.

Drop --experimental-bootstrap-token-auth flag.
**What this PR does / why we need it**:
Drops support for the `--experimental-bootstrap-token-auth` flag for the API server. This flag was replaced by `--enable-bootstrap-token-auth` in 1.8 (https://github.com/kubernetes/kubernetes/pull/51198) but the old flag was accepted with a deprecation warning. In 1.9 we want to totally drop it.
**Which issue this PR fixes**: fixes#50613
**Special notes for your reviewer**:
There are other places in kubeadm where we need to drop support for this flag (at init and at postupgrade). We can tackle those in a separate PR.
**Release note**:
I think this change is already document well enough in the changelog for 1.8.

Add Windows Server Containers Stats and Metrics to Kubelet
**What this PR does / why we need it**:
This PR implements stats for Windows Server Containers. This adds the ability to monitor Windows Server containers via the existing stats/summary endpoint inside the kubelet. Windows metrics can now be ingested into heapster and monitored using existing tools (like Grafana).
Previously, the /stats/summary api would consistently crash the kubelet on Windows server containers. This PR implements a new package "winstats" which reads windows server metrics from a combination of windows specific perf counters as well as docker stats. The "winstats" package exports functions that return CAdvisor data structures, which the existing summary api can read.

Fix incorrect status msg in podautoscaler
**Which issue this PR fixes**
Fix#49256
**What this PR does / why we need it**:
When `ScalingLimited = true` for the `hpa`, there is an accompanying
status message, describing why scaling is limited. Previously if the desired
replica count was 0, and spec.minReplicas > 0, the status message
indicated "the desired replica count was less than the min replica
count". This was particularly confusing when `spec.MinReplicas = 1`. If
there was no `spec.minReplicas`, then the status message indicated "the
desired replica count was zero" which is more informative.
Update the calculation of status message so that if the desired replica
count is 0, we always display the clearer "the desired replica count was
zero" status message, even if spec.minReplicas > 0.

Azure cloud provider: expose services on non-default subnets
**What this PR does / why we need it**: The Azure cloud provider allows users to specify that a service should be exposed on an internal load balancer instead of the default external load balancer. However, in a VNet environment, such services are currently always exposed on the master subnet. Where there are multiple subnets in the VNet, it's desirable to be able to expose an internal service on any subnet. This PR allows this via a new annotation, `service.beta.kubernetes.io/azure-load-balancer-internal-subnet`.
**Which issue this PR fixes**: fixes https://github.com/Azure/acs-engine/issues/1296 (no corresponding issue has been raised in the k8s core repo)
**Special notes for your reviewer**: None
**Release note**:
```release-note
A new service annotation has been added for services of type LoadBalancer on Azure,
to specify the subnet on which the service's front end IP should be provisioned. The
annotation is service.beta.kubernetes.io/azure-load-balancer-internal-subnet and its
value is the subnet name (not the subnet ARM ID). If omitted, the default is the
master subnet. It is ignored if the service is not on Azure, if the type is not
LoadBalancer, or if the load balancer is not internal.

Fix AnnotationProvidedIPAddr annotation for externalCloudProvider
**What this PR does / why we need it**:
In #44258, it introduced `AnnotationProvidedIPAddr`. When kubelet has 'node-ip' parameter set, and cloud provider not set, this annotation would be populated, and then will be validated by cloud-controller-manager:
https://github.com/kubernetes/kubernetes/pull/44258/files#diff-6b0808bd1afb15f9f77986f4459601c2R465
Later with #47152, externalCloudProvider is checked and func returns before that annotation got set. In this case, that annotation will not get populated.
This fix is to bring that annotation assignment to a proper location.
Please correct me if I have any misunderstanding.

Adds a command-line argument to kube-apiserver called

reconciler uses the storageapi and a TTL to keep alive an endpoint within the
`kube-apiserver-endpoint` storage namespace. The 'none' reconciler is a noop
reconciler that does not do anything. This is useful for self-hosted
environments.

Do deep copy instead of to and from JSON encoding
**What this PR does / why we need it**:
Unstructured converter encodes to JSON and then parses the result into a new object. For `Unstructured` this can be avoided by directly doing a deep copy. It is an optimization.
**Special notes for your reviewer**:
#47889 is somewhat related.

inode eviction tests fill a constant number of inodes
Issue: #52203
inode eviction tests pass often on some OS distributions, and almost never on others. See [these testgrid tests](https://k8s-testgrid.appspot.com/sig-node#kubelet-flaky-gce-e2e&include-filter-by-regex=Inode)
These differences are most likely because different images have fewer or greater inode capacity, and thus percentage based rules (e.g. inodesFree<50%) make the test more stressful for some OS distributions than others.
This changes the test to require that a constant number of inodes are consumed, regardless of the number of inodes in the filesystem, by setting the new threshold to:
nodefs.inodesFree<(current_inodes_free - 200k)
so that after pods consume 200k inodes, they will be evicted. It requires querying the summary API until we successfully determine the current number of free Inodes.

ignore unknown resource version in scaler error
**Release note**:
```release-note
NONE
```
Rather than printing `Scaling the resource failed with: An Error; Current resource version Unknown` whenever a ScalerError occurs and a resource version is not known, we should avoid printing the resource version part of the error message in order to avoid potential confusion by a user.

adding kube-controller-manager starting option tests
**What this PR does / why we need it**:
The unit test for kube-controller-manager is missing in `cmd/kube-controller-manager/app/options`. I have added a unit test for checking kube-controller-manager starting options, which is similar to the unit test in `cmd/kube-apiserver/app/options/options_test.go`. This PR https://github.com/kubernetes/kubernetes/pull/49092 can be seen as a reference.
