saadali 542f2dc708 Introduce new kubelet volume manager
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.

Jan Safranek 0ee9160f88 volume recycler: Don't start a new recycler pod if one already exists.
Recycling is a long duration process and when the recycler controller is
restarted in the meantime, it should not start a new recycler pod if there is
one already running.

This means that the recycler pod must have deterministic name based on name
of the recycled PV, we then get name conflicts when creating the pod.

Two things need to be changed:
- recycler controller and recycler plugins must pass the PV.Name to place,
  where the pod is created.

- create recycler pod with deterministic name and check "already exists" error.

When at it, remove useless 'resourceVersion' argument and make log messages
starting with lowercase.

Eric Paris f125ad88ce Rename IsMountPoint to IsLikelyNotMountPoint
IsLikelyNotMountPoint determines if a directory is not a mountpoint.
It is fast but not necessarily ALWAYS correct. If the path is in fact
a bind mount from one part of a mount to another it will not be detected.
mkdir /tmp/a /tmp/b; mount --bin /tmp/a /tmp/b; IsLikelyNotMountPoint("/tmp/b")
will return true. When in fact /tmp/b is a mount point. So this patch
renames the function and switches it from a positive to a negative (I
could think of a good positive name). This should make future users of
this function aware that it isn't quite perfect, but probably good
enough.
