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.
This patch cleans up pkg/util/mount/* and pkg/util/volume/* to always
use filepath.Join instead of path.Join. filepath.Join is preferred
because path.Join can have issues on Windows.
- 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

Since the runtime may try to create mount points within
the sandbox, it will fail if the mount point is within
a read-only API data volume, like a secret or configMap
volume.
Create any needed mount points during volume setup.

Rework method of updating atomic-updated data volumes
**What this PR does / why we need it**:
This change affects the way that secret, configmap, downwardAPI and projected volumes (which all use the same underlying code) implement their data update functionality.
* Instead of creating a subdirectory hierarchy that will contain symlinks to each actual data file, create only symlinks to items in the root of the volume, whether they be files or directories.
* Rather than comparing the user-visible data directory to see if an update is needed, compare with the current version of the data directory.
* Fix data dir timestamp format year
* Create `..data` symlink even when a data volume has no data so consumers can have simplified update watch logic.
**Which issue(s) this PR fixes**:
Fixes#57421
**Release note**:
```release-note
Correct issues that arise when volumes are mounted beneath another secret, configmap, downwardAPI or projected volume
