Subject: Scripts to identify quota accouting issues

The patch contains 2 scripts:

log_accounting.sh does a du -h on the FS hierarchy and a quota list
on the hierarchy and interleaves the two output. We can then identify
which directory(s) in FS has caused the accounting to go bad and try
to investigate what fops happened on those directories. We can also
limit the set of directories on which we need to set dirty xattr to
correct accounting.
xattr_analysis.py reads all the xattr of a brick and dumps it a human
readable form to ease debugging.
