Add custom volume name based on SC parameter.
At present glusterfs dynamic PVs are created with
random names. However an admin would like to have some
handle on the volume names created dynamically for
various purposes. One example would be having a filter
for sorting out PVs created for a particular storage class.
This patch enables the functionality by having a custom
volume name as a prefix to dynamic PVs. This is an optional
parameter in SC and if set, the dynamic volumes are created
in below format where `_` is the field seperator/delimiter:

git: Use VolumeHost.GetExec() to execute stuff in volume plugins
This prepares volume plugins to run things in containers instead of running
them on the host.
**Special notes for your reviewer**:
* instead of `cmd.SetDir(<dir>); cmd.Exec("git <command>")`, we do `cmd.Exec("git -C <dir> <command>")` - mounter.Exec does not have SetDir()
* there are lot of changes in the tests because a different exec interface is used.

Fix quota controller worker deadlock
The resource quota controller worker pool can deadlock when:
* Worker goroutines are idle waiting for work from queues
* The Sync() method detects discovery updates to apply
The problem is workers acquire a read lock while idle, making write lock
acquisition dependent upon the presence of work in the queues.
The Sync() method blocks on a pending write lock acquisition and won't unblock
until every existing worker processes one item from their queue and releases
their read lock. While the Sync() method's lock is pending, all new read lock
acquisitions will block; if a worker does process work and release its lock, it
will then become blocked on a read lock acquisition; they become blocked on
Sync(). This can easily deadlock all the workers processing from one queue while
any workers on the other queue remain blocked waiting for work.
Fix the deadlock by refactoring workers to acquire a read lock *after* work is
popped from the queue. This allows writers to get locks while workers are idle,
while preserving the worker pause semantics necessary to allow safe sync.
```release-note
Fixes an infrequent problem causing the resource quota controller to become stuck in clusters with low ResourceQuota churn, potentially preventing quota from being recalculated until the controller is restarted or until bursts of diverse quota activity unstick the controller.

GCE: Use existing subnetwork of ILB forwarding rule
Fixes#57860
**Test Cases**:
Clusters using auto network with existence of a manual subnet in same region.
- [x] Upgrade 1.7 cluster with existing ILBs to latest. Confirm existing ILBs still are synced.
Version 1.7 does not attempt to fill in the subnetwork, so the forwarding rule was created with the correct subnetwork.
- [x] Upgrade 1.8 cluster with existing ILBs to latest. Confirm existing ILBs (using wrong subnet) still are synced.
- [x] Latest version creates ILBs using the correct subnet.
Clusters with manual subnets have always and will continue to use the subnet specified in gce.conf.
- [x] Upgrade 1.8 cluster with existing ILBs to latest. Confirm existing ILBs (using manual subnet) still are synced.
Clusters with legacy networks have always and will continue to use an empty subnet.
- [x] Upgrade 1.8 cluster with existing ILBs to latest. Confirm existing ILBs (using legacy network) still are synced.

Code generation for GCE compute interface
Use code generation to "write" most of the GCE cloud provider library. This enables the following:
- Consistent interfaces, including handling of the different API versions (GA, alpha, beta)
- Efficient implementation of cross cutting features such as metrics, logging, tracing etc. Adding such features has in the past been a tedious and error prone endeavor.
- High fidelity mocks for all of the compute API. What this means is that most of our controller logic can be tested as unit tests in a consistent way without creating individual mocks by hand.

Fixes#57952
**Special notes for your reviewer**:
this is a corresponding fix of https://github.com/kubernetes/kubernetes/pull/57549, #57549 uses '/dev/disk/by-id', and this PR would check whether the mountPath is valid when kubelet restart(e.g. after VM reboot since device name may change), if not valid, remount, remember '/dev/disk/by-id' will be always valid.
**Release note**:
```
fix device name change issue for azure disk: add remount logic
```

Explicit kubelet flags
The Kubelet was using the global flag set.
Libraries also often use the global flag set.
There are flags in the Kubelet's usage statement for which the Kubelet does not control registration.
This is bad, we must have full control of our command-line API.
This PR puts a stop to it.
I worked through the Kubelet's usage printout and tracked down the flags.
In the below list, flags with checkboxes are one of:
- explicitly **registered** in this PR
- thought about and outright **rejected**
- thought about and **registered-deprecated** for legacy reasons
For the others we need to figure out whether they should be **registered** or **rejected** or **registered-deprecated**.

```release-note
The Kubelet now explicitly registers all of its command-line flags with an internal flagset, which prevents flags from third party libraries from unintentionally leaking into the Kubelet's command-line API. Many unintentionally leaked flags are now marked deprecated, so that users have a chance to migrate away from them before they are removed. One previously leaked flag, --cloud-provider-gce-lb-src-cidrs, was entirely removed from the Kubelet's command-line API, because it is irrelevant to Kubelet operation.
```
Thanks to @liggitt for being surprised that we didn't already do this.
Thanks to @dashpole for realizing cadvisor flags were leaked after seeing #55863.
Thanks to @tallclair who recognized this problem a long time ago in #19432.

This explicitly registers Kubelet flags from libraries that were
registering flags globally, and stops parsing the global flag set.
In general, we should always be explicit about flags we register
and parse, so that we maintain control over our command-line API.
This patch adds missing value to a format string (%s) in --restart flag
validation for "kubectl run".
"kubectl run --restart=foo" was giving error:
error: invalid restart policy: %!s(MISSING)
Now it says:

Renews cached NodeInfo with new vSphere connection
**What this PR does / why we need it**:
This PR modifies two public functions of nodemanager.go- GetNodeInfo and GetNodeDetails. For both these functions NodeInfo object is renewed with new GoVmomiClient and new vclib VirtualMachine and Datacenter.
**Which issue(s) this PR fixes** :
Fixes vmware#404
**Special notes for your reviewer**:
Code has been structured to minimize impact on existing 1.9 release code and any side-effects due to NodeInfo modification. This is a quick solution for vSphere connection renewal problem. A more enhanced solution is target for upcoming major release.
Testing:
- [x] Successfully tried out pod creation, deletion with dynamic volume.
- [x] Successfully ran e2e tests.
**Release note**:
```release-note

```
It's interesting that those service does not need loadbalancer, and caller is just checking whether one loadbalancer exists.
009701f181/pkg/controller/service/service_controller.go (L287)
And in we can see when err is not nil, it will not check exists value. Thus we should not return error when exists=false.
This was changed in:
edfb2ad552 (diff-c901394068476b4ccb003a6c6efad57cR63)
The PR removes the error when exists=false.

Adding support for Block Volume type to rbd plugin.

NFS plugin should not use IsLikelyNotMountPoint(), as it uses lstat() / stat()
to determine if the NFS volume is still mounted - NFS server may use
root_squash and kubelet may not be allowed to do lstat() / stat() there.
It must use slower IsNotMountPoint() instead, including TearDown() function.
