Instead of using mount api to mount the snap device, use runner apis
to execute the mount command which mounts the snap device.

Fetching snap mount path per brick during pre-validate
and aggregating it before commit to generate all brick
volfiles and all client volfiles on all nodes.
Added changes to propagate the same cg-id by generating
it in pre-validate and sending the same to all the nodes
during commit
Also fixed volume-id mismatches caused in snap-volumes
leading to failures of volume status

In RHEL ACTIVATION_SKIP flag is set by default. Using
'--setactivationskip n' during lvcreate activates the
logical volumes upon creation.

Suppose a volume's brick has the path /export/brick/vol/dir and lvm
of that brick is mounted at /export. Now snap of that brick is
taken, and is mounted on a path (say /run/gluster/snaps/<snapname>)
While creating the brick for the snap volume, /run/gluster/snaps/<snapname>
(i.e the mount point of the snap lvm) should not be used as the export
directory. The directory path remaining after the mount point of the
original lvm should be appended to the snap lvm mounted path and
should be used as the export directory
(ex: /run/gluster/snaps/<snapname>/brick/vol/dir in this case).
Its because the volume-id of the original volume and other extended
attributes wont be set on the root. It will be in the same path as the
original lvm.

GL-31: Ability to restore snapshot
Implemented snapshot restore for thin logical volume. As of now snapshot
restore for CG is not tested. Testing for snapshot restore of a volume
is done by changing the snapshot create process to create a thick snapshot.
This is done because --merge option to restore thin volume is not working in
the latest kernel.

Change in Naming convention:
"snap_details", "snap_count" and so on
is replaced by "snap-details", "snap-count" so on.
Total snapcount introduced.
Separate check is made for repeated Volume Name
Ex : "gluster snapshot list vol1 vol2 vol1 vol2"
is considered as "gluster snapshot list vol1 vol2"
*This is still a work in progress*
*have to test CG list once CG Store is ready*

This is still a work in progress.
As of now, these things are done:
* Take the snapshot of the backend brick
* Create the new volume for the snapshot
* Create the brick and the client volfiles
* Store the snapshot related info in /var/lib/glusterd
* Create the snap object representing the snapshot
TODO:
Start the brick processes for the snapshot
