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
