This patch removes pkg/util/mount completely, and replaces it with the
mount package now located at k8s.io/utils/mount. The code found at
k8s.io/utils/mount was moved there from pkg/util/mount, so the code is
identical, just no longer in-tree to k/k.
- Rename MapDevice to MapPodDevice in BlockVolumeMapper
- Add UnmapPodDevice in BlockVolumeUnmapper (This will be used by csi driver later)
- Add CustomBlockVolumeMapper and CustomBlockVolumeUnmapper interface
- Move SetUpDevice and MapPodDevice to CustomBlockVolumeMapper
- Move TearDownDevice and UnmapPodDevice to CustomBlockVolumeUnmapper
- Implement CustomBlockVolumeMapper only in local and csi plugin
- Implement CustomBlockVolumeUnmapper only in fc, iscsi, rbd, and csi plugin
- Change MapPodDevice to return path and SetUpDevice not to return path
This patch removes mount.Exec entirely and instead uses the common
utility from k8s.io/utils/exec.
The fake exec implementation found in k8s.io/utils/exec differs a bit
than mount.Exec, with the ability to pre-script expected calls to
Command.CombinedOutput(), so tests that previously relied on a callback
mechanism to produce specific output have been updated to use that
mechanism.
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

Currently, FC plugin returns volume name and empty
FCVolumeSource during ConstrutVolumeSpec during
filesystem volume's reconstruction.
In this fix, ConstructVolumeSpec retrieves global
mount path, analyzes volume parameters such as
WWN, LUN, WWID from the path.
Fixes#58085

Refactoring and improvements for iSCSI and FC storage plugins
**What this PR does / why we need it**:
This PR makes following changes.
- Simplify volume tearDown path for iSCSI and FC using
util.UnmountPath().
- Log lastErr during iscsi connection
If iscsid fails to connect second portal, currently
the error is ignored silently. The lastErr should be
logged to find the root cause of problem.
- Remove iscsi plugin directory after iscsi connection
is successfully closed.
**Which issue this PR fixes** : No related issues.
**Special notes for your reviewer**:
/cc @rootfs @jsafrane
**Release note**:
```
NONE
```
At volume attach/detach controller, GetVolumeName() is
expected to return unique volume identifier, but FC
plugin didn't return unique identifier if user specified
FC volume using target wwn and lun.
In order to return unique identifier, GetVolumeName()
should use combination of target wwn and lun.
Fixes#52690

This implements Bulk volume polling using ideas presented by
justin in https://github.com/kubernetes/kubernetes/pull/39564
But it changes the implementation to use an interface
and doesn't affect other implementations.
