extras: clean up a brick's gfid xattr

Browse Source 
* extras/clear_xattrs.sh: This script enables a brick from a
deleted volume(stale brick) to be used in a new volume by
clearing all the trusted.gfid xattr from the brick tree.

* One should run this script on all machines which have
stale bricks if one wants to re-use the same bricks
for a new volume.

NOTE: This script *SHOULD BE RUN ONLY AFTER STOPPING A VOLUME*,
thereby ensuring that no replace-brick or rebalance operations
are on-going.
