Currently, there are some unit tests that are failing on Windows due to
various reasons:
- volume mounting is a bit different on Windows: Mount will create the
parent dirs and mklink at the volume path later (otherwise mklink will
raise an error).
- os.Chmod is not working as intended on Windows.
- path.Dir() will always return "." on Windows, and filepath.Dir()
should be used instead (which works correctly).
- on Windows, you can't typically run binaries without extensions. If
the file C:\\foo.bat exists, we can still run C:\\foo because Windows
will append one of the supported file extensions ($env:PATHEXT) to it
and run it.
- Windows file permissions do not work the same way as the Linux ones.
- /tmp directory being used, which might not exist on Windows. Instead,
the OS-specific Temp directory should be used.
Fixes a few other issues:
- rbd.go: Return error in a case in which an error is encountered. This
will prevent "rbd: failed to setup" and "rbd: successfully setup" log
messages to be logged at the same time.

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 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.
This patch moves fake.go to mount_fake.go, and follows to principle of
always returning a discrete type rather than an Interface. All callers
of "FakeMounter" are changed to instead use "NewFakeMounter()". The
FakeMounter "Log" struct member is changed to not be exported, and
instead only access through a new "GetLog()" method.
This commit adds a new volume manager in kubelet that synchronizes
volume mount/unmount (and attach/detach, if attach/detach controller
is not enabled).
This eliminates the race conditions between the pod creation loop
and the orphaned volumes loops. It also removes the unmount/detach
from the `syncPod()` path so volume clean up never blocks the
`syncPod` loop.
