glusterd: cli command implementation for bitrot scrub status

This patch is backport of: http://review.gluster.org/10231

CLI command  for bitrot scrub status will be :

gluster volume bitrot <volname> scrub status

Above command will show the statistics of bitrot scrubber.

Upon execution of this command it will show some common
scrubber tunable value of volume <VOLNAME> followed by
statistics of scrubber statistics of individual nodes.

sample ouput for single node:

Volume name : <VOLNAME>

State of scrub: Active

Scrub frequency: biweekly

Bitrot error log location: /var/log/glusterfs/bitd.log

Scrubber error log location: /var/log/glusterfs/scrub.log

=========================================================

Node name:

Number of Scrubbed files:

Number of Unsigned files:

Last completed scrub time:

Duration of last scrub:

Error count:

=========================================================

This is just infrastructure. list of bad file, last scrub
time, error count value will be taken care by
http://review.gluster.org/#/c/12503/  and
http://review.gluster.org/#/c/12654/ patches.
