extras: clean up a brick's gfid xattr
* 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.
