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.

Matt Dainty 8bbc86d83c Override the GlusterFS log file location 
GlusterFS by default uses a log file based on the mountpoint path munged into a
file, i.e. `/mnt/foo/bar` becomes `/var/log/glusterfs/mnt-foo-bar.log`.

On certain Kubernetes environments this can result in a log file that exceeds
the 255 character length most filesystems impose on filenames causing the mount
to fail. Instead, use the `log-file` mount option to place the log file under
the kubelet plugin directory with a filename of our choosing keeping it fairly
persistent in the case of troubleshooting.

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.
