StorageOS configurable device directory and mount options
**What this PR does / why we need it**:
This allows StorageOS volumes to be mounted when the kubelet is running in a container and we are unable to use the default device location (/var/lib/storageos/volumes). With this PR, the node's device location is requested via the StorageOS api, falling back to the current behaviour if not configured. The node's device location can be supplied as an environment variable (DEVICE_DIR) to the StorageOS container. This is backwards-compatible and no changes are needed to existing deployments.
The PR also allows Mount options to be set for StorageOS volumes in the same way they're enabled for other volume plugins.
The StorageOS API dependency was updated to the latest version, but no functionality changes besides adding the DeviceDir property to the Controller object.
There is also a small refactor of the loopback device handling code in storageos_utils.go to capture stderr output.
**Release note**:
```release-note
StorageOS volume plugin updated to support mount options and environments where the kubelet runs in a container and the device location should be specified.
```

Fix issue #55031 to remove dependence on package lxn/win
**What this PR does / why we need it**:
This PR fixes issue #55031 where kubelet.exe crashes on Windows Server Core. The root cause is that kubelet.exe depends on package lxn/win pdh and kernel32 wrapper for node metrics. However, opengl32.dll is not available in Server Core and lxn/win requires the presence of all win32 DLLs.
This PR uses a slim win32 package JeffAshton/win_pdh since most win32 APIs needed are PDH API. Also this PR makes own implementation of GetPhysicallyInstalledSystemMemory until golang Windows syscall has it or lxn/win fixes opengl32 issue. Also this PR modifies the way to get Windows version.

Remove Google Cloud KMS's in-tree integration
Removes the following introduced by #48574 and others:
* `kms.go` which contained the cloudkms-specific code for Google Cloud KMS service.
* Registering the Google Cloud KMS in the KMS plugin registry.
* Google's `cloudkms` API package from `vendor` folder.
The following changes are upcoming:
* Removal of KMSPluginRegistry. This would not be needed anymore, since KMS providers will be out-of-tree from now on (so no need of registering them, an address of the process would be enough).
* A service which allows encrypt/decrypt functionality (satisfies `envelope.Service` interface) if initialized with an IP/Port of an out-of-tree process serving KMS requests. Will tentatively use gRPC requests to talk to this external service.
Reference: https://github.com/kubernetes/kubernetes/pull/54439#issuecomment-340062801 and https://github.com/kubernetes/kubernetes/issues/51965#issuecomment-339333937.

Fix the version detection of OpenStack Cinder
**What this PR does / why we need it**:
When running Kubernetes against an installation of DevStack which
deploys the Cinder service at a path rather than a port (ex:
http://foo.bar/volume rather than http://foo.bar:xxx), the version
detection fails. It is better to use the OpenStack service catalog.
OTOH, when initialize cinder client, kubernetes will check the
endpoint from the OpenStack service catalog, so we can do this
version detection by it.
There are two case should be fixed in other PR:
1. revisit the version detection after supporting Cinder V3 API.
2. add codes to support MicroVersion after gophercloud supports MicroVersion.

Remove cloud provider rackspace

For now, we have to implement functions in both `rackspace` and `openstack` packages if we want to add function for cinder, for example [resize for cinder](https://github.com/kubernetes/kubernetes/pull/51498).

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.

Kubectl to use http caching to cache openapi responses from the server
**What this PR does / why we need it**:
This PR is trying to address the problems raised in #50254
> * uses a disk-based cache that is not safe between processes (does not use atomic fs operations)
> * writes get/list responses to disk that should not be cached (like kubectl get secrets)
> * is vulnerable to partially written cache responses being used as responses to future requests
> * breaks uses of the client transport that make use of websockets
> * defaults to enabling the cache for any client builder using RecommendedConfigOverrideFlags or DefaultClientConfig which affects more components than just kubectl
All of these points are addressed by this pull-request:
1. It now uses atomic fs operations
2. Doesn't cache by default, only if requested by the client (and it's only done by openapi client)
3. Fixed because of atomic fs operations
4. Found the reason for the bug: Cache wrapper couldn't be unwrapped. I implemented the `WrappedRoundTripper` interface.
5. Since 2. is fixed, I think that should be fine

Add support for IP aliases for pod IPs (GCP alpha feature)
```release-note
Adds support for allocation of pod IPs via IP aliases.
# Adds KUBE_GCE_ENABLE_IP_ALIASES flag to the cluster up scripts (`kube-{up,down}.sh`).
KUBE_GCE_ENABLE_IP_ALIASES=true will enable allocation of PodCIDR ips
using the ip alias mechanism rather than using routes. This feature is currently
only available on GCE.
## Usage
$ CLUSTER_IP_RANGE=10.100.0.0/16 KUBE_GCE_ENABLE_IP_ALIASES=true bash -x cluster/kube-up.sh
# Adds CloudAllocator to the node CIDR allocator (kubernetes-controller manager).
If CIDRAllocatorType is set to `CloudCIDRAllocator`, then allocation
of CIDR allocation instead is done by the external cloud provider and
the node controller is only responsible for reflecting the allocation
into the node spec.
- Splits off the rangeAllocator from the cidr_allocator.go file.
- Adds cloudCIDRAllocator, which is used when the cloud provider allocates
the CIDR ranges externally. (GCE support only)
- Updates RBAC permission for node controller to include PATCH
