This PR fixes issue #32727.
When an attach operation fails, it is still possible that the volume
will be attached to the node later. This PR adds the logic to record the
volume to node with attached state no matter whether the operation
succedded or not. If the operation fails, mark the attached state to
false. If the operation succeeded, mark the attached state to true. The
reconciler will still issue attach operation until it returns
successfully. If the pod is removed in the mean time, the reconciler
will issue detach operations for all the volumes no matter what is the
attached state.
- 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

- Change not to skip error from GetLoopDevice other than DeviceNotFound
- Add comment for the reason for order of descriptor lock release and TearDownDevice

[RBD block device ]ignore the loopbackdevice error, or the rbd volume will not get detached
The rbd volume loop device maybe not found and then the volume will not get detached.
so need to ignore the error.

Can you take a look?
Release note:
```
ignore the loopback device not found error when `GetLoopDevice`
```

Add volume spec to mountedPod in actual state of world
Add volume spec into mountedPod data struct in the actual state of the
world.
Fixes issue #61248
Users must not be allowed to step outside the volume with subPath.
Therefore the final subPath directory must be "locked" somehow
and checked if it's inside volume.
On Windows, we lock the directories. On Linux, we bind-mount the final
subPath into /var/lib/kubelet/pods/<uid>/volume-subpaths/<container name>/<subPathName>,
it can't be changed to symlink user once it's bind-mounted.
If plugin is non-attachable, global unmap path isn't stored in asw
then plugin fails to unmap volume. To store the path, this PR moves
MarkDeviceAsMounted operation from the `if volumeAttacher != nil` block.

Redesign and implement volume reconstruction work
This PR is the first part of redesign of volume reconstruction work. The detailed design information is https://github.com/kubernetes/community/pull/1601
The changes include
1. Remove dependency on volume spec stored in actual state for volume
cleanup process (UnmountVolume and UnmountDevice)
Modify AttachedVolume struct to add DeviceMountPath so that volume
unmount operation can use this information instead of constructing from
volume spec
2. Modify reconciler's volume reconstruction process (syncState). Currently workflow
is when kubelet restarts, syncState() is only called once before
reconciler starts its loop.
a. If volume plugin supports reconstruction, it will use the
reconstructed volume spec information to update actual state as before.
b. If volume plugin cannot support reconstruction, it will use the
scanned mount path information to clean up the mounts.
In this PR, all the plugins still support reconstruction (except
glusterfs), so reconstruction of some plugins will still have issues.
The next PR will modify those plugins that cannot support reconstruction
well.
This PR addresses issue #52683

Improve messaging on volume expansion
- we now provide clear message to user what to do when cloudprovider resizing is finished
and file system resizing is needed.
- add a event when resizing is successful
- Use PATCH both in controller-manager and kubelet for updating PVC status
- Remove code duplication between controller-manager and kubelet for updating PVC status
- Only remove conditions that are managed by resize controller
```release-note
Improve messages user gets during and after volume resizing is done.

format error message and remove duplicated event for resize volume failure
**What this PR does / why we need it**:
1. The `operationGenerator.resizeFileSystem` method returns errors generated by `volumeToMount.GenerateErrorDetailed`, and the outside code(`operationGenerator.GenerateMountVolumeFunc`) uses `volumeToMount.GenerateError` to generate a new error again, which lead to the event message redundant and confused, we should use `volumeToMount.GenerateError` inside `operationGenerator.resizeFileSystem` only, in outside code is not necessary.
2. The `eventRecorderFunc` will record an event if `resizeFileSystem` returns an error, so we needn't to record event inside `resizeFileSystem` itself.
**Release note**:
```release-note
NONE

Improved mount/attach error logging and added attach event.
Fixed kubelet error message to be more descriptive. Added Attach success event for help in debugging.
The attach event is helpful when the node may not have the correct information about attachment status, it allows the user to see whether the Attach was run at all. If there is no success/failure attach message we can infer that there was no attach started at all.
Fixes#57217
