When a block device, say /dev/sdc, is unexpectedly disconnected from a node,
the corresponding backing file path found at /sys/block/loop*/backing_file gets
a "(deleted)" suffix. This patch trims that suffix out, allowing the Kubelet to
unmount the volume correctly.

The non "util-linux" versions of "losetup" don't seem to have
options like "-j" ("--associated") which lists the loop devices
associated with the file, or "--show" which displays the name
of the assigned loop device for a file.
For instance, when "-j" is used, "GetLoopDevice()" fails with:
$ losetup -j /path/to/file
losetup: unrecognized option: j
BusyBox v1.32.1 () multi-call binary.
Add a fallback option to lookup the device from "sysfs" in cases
where "losetup" fails for an invalid option. This can be done by
reading the backing file from "/sys/block/loop*/loop/backing_file"
for each of the devices listed there.

In case /var/lib/kubelet is a symlink, "losetup -j <device in
/var/lib/kubelet>" will show the device paths with symlinks fully
evaluated.
Fix the parsing routine and expand symlinks in the path that we want to
find in "losetup -j" output.
This change is needed to make descriptor lock per pod, in the next commit.
If losetup is called for symlink, path in the output for losetup is resolved,
as a result, we can't distinguish which path the lock is taken.
- 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
