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

We were not sorting them previously, which made the order
non-deterministic. If we believe the order doesn't matter, let's pick
a consistent order to minimize the chances of a rare flake.
This also simplifies the unit tests, which were flaking
not-very-rarely, e.g. with
`bazel test //pkg/volume/awsebs/... --runs_per_test=8`
- Change not to skip error from GetLoopDevice other than DeviceNotFound
- Add comment for the reason for order of descriptor lock release and TearDownDevice
From current AWS documentation:
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/volume_limits.html
T3, C5, C5d, M5, M5d, R5, R5d, and z1d instances support a maximum of
28 attachments, and every instance has at least one network interface
attachment. If you have no additional network interface attachments on
these instances, you could attach 27 EBS volumes.

Ignore EIO error in unmount path
**What this PR does / why we need it**:
This PR ignores EIO in unmount path. XFS shuts down filesystem when the target is down and it returns EIO for the stat calls used in unmount path.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes#66868
**Special notes for your reviewer**:
We already handle ESTALE & ENOTCONN errors in isCorruptedMnt Call. Adding EIO to that list covers the XFS shutdown case.
Also Flexvolume doesn't check for these errors in its current form. Updated Flexvolume code to handle it.
