    Backport of http://review.gluster.org/#/c/14018/

snap status --xml errors out if a brick is down and
doesn't have pid. It is handled in the cli of the snap
status where "N/A" is displayed in such a scenario.
Handled the same in xml

snap status <snapname> --xml fails as the writer is
not initialised for the same. Using GF_SNAP_STATUS_TYPE_ITER
instead of GF_SNAP_STATUS_TYPE_SNAP for all snap's
status to differentiate between the two scenarios.

Added testcase volume-snapshot-xml.t to check
all snapshot commands xml outputs

fix: The cold bricks tag included the processes also.
The patch has removed the processes from being mentioned
inside the cold brick tag and are mentioned below by 
closing the cold brick tag after the brick count.

Currently When hot tier type is distributed-replicate and cold tier
type is disperse volume then #gluster volume info --xml command is
not giving its correct output. In case of HOT tier case its displaying
wrong volume type.

With this fix it will show correct xml output for tier volume
irrespective of all the type of the volume's.

Problem:
As of now quota 'list/list-objects' will list the usage only if limit is
set for every directory else it will fail with ENOATTR(If inode/inode-quota
is already configured for the first time).

Feature:
With the patch we are enhancing this command to list the usage even
if quota limit is not set but still the user has to configure
inode/inode-quota for the first time.

Example:
Consider we have /client/dir and /client1(absolute path from mount point):
Quota limit is set only on /client. when we try listing /client/dir or /client1,
it shows "Limit not set".

Fix:
The patch fixes this by showing "used space" in case of list command and
shows "file_count" & "dir_count" in case of list-objects command. This works
fine with xml output as well.
