Initial basic bootstrap-checkpoint support
**What this PR does / why we need it**:
Adds initial support for Pod checkpointing to allow for controlled recovery of the control plane during self host failure conditions.
fixes#49236
xref https://github.com/kubernetes/features/issues/378
**Special notes for your reviewer**:
Proposal is here: https://docs.google.com/document/d/1hhrCa_nv0Sg4O_zJYOnelE8a5ClieyewEsQM6c7-5-o/edit?ts=5988fba8#
1. Controlled tests work, but I have not tested the self hosted api-server recovery, that requires validation and logs. /cc @luxas
2. In adding hooks for checkpoint manager much of the tests around basicpodmanager appears to be stub'd. This has become an anti-pattern in the code and should be avoided.
3. I need a node-e2e to ensure consistency of behavior.
**Release note**:
```
Add basic bootstrap checkpointing support to the kubelet for control plane recovery
```

Fixes issue where PVCs using `standard` StorageClass create PDs in disks in wrong zone in multi-zone GKE clusters
Fixes#50115
Changed GetAllZones to only get zones with nodes that are currently running (renamed to GetAllCurrentZones). Added E2E test to confirm this behavior.

Updating vsphere cloud provider to support k8s cluster spread across multiple vCenters
**What this PR does / why we need it**:
vSphere cloud provider in Kubernetes 1.8 was designed to work only if all the nodes of the cluster are in one single datacenter folder. This is a hard restriction that makes the cluster not span across different folders/datacenter/vCenters. Users have use-cases to span the cluster across datacenters/vCenters.
**Which issue(s) this PR fixes**
Fixes # https://github.com/vmware/kubernetes/issues/255
**Special notes for your reviewer**:
This is a change purely in vsphere cloud provider and no changes in kubernetes core are needed.
**Release note**:
```release-note
With this change
- User should be able to create k8s cluster which spans across multiple ESXi clusters, datacenters or even vCenters.
- vSphere cloud provider (VCP) uses OS hostname and not vSphere Inventory VM Name.
That means, now VCP can handle cases where user changes VM inventory name.
- VCP can handle cases where VM migrates to other ESXi cluster or datacenter or vCenter.
The only requirement is the shared storage. VCP needs shared storage on all Node VMs.
```
Internally tested and reviewed the code.
@tthole, @shaominchen, @abrarshivani
running (renamed to GetAllCurrentZones). Added E2E test to confirm this
behavior.
Added node informer to cloud-provider controller to keep track of zones
with k8s nodes in them.

RBD Plugin: Fix bug in checking command not found error.
**What this PR does / why we need it**:
Fix bug in error checking logic.
`Error()` method of command not found error returned from `command.Run/Output` is not "executable file not found in $PATH". Actually, it's `exec: "<command>": executable file not found in $PATH`.
I followed the logic in https://github.com/kubernetes/kubernetes/blob/v1.9.0-alpha.1/pkg/kubectl/cmd/util/editor/editor.go#L129 to detect command not found error.

Rename Detach() parameter.
`Detach()` does not get device name, it gets volume name. Parameters named `deviceMountPath` or `deviceName` just confuses developers.
Note that this PR just renames parameters here and there, there should be no behavior change.

Remove dependency on drv_cfg binary for querying ScaleIO devices
**What this PR does / why we need it**:
This PR fixes the issue where a ScleIO kubernetes plugin required additional binary `drv_cfg` to be present on the local node to work properly, making it harder for the kubelet binary to be containerized without providing access to local paths inside the container.
