COMMIT: https://review.gluster.org/16778 committed in master by "Amar Tumballi" <amarts> with a commit message- extras/devel-tools: script to strace processes

Script to strace processes at high priority.
Script should be run at high priority, like nice value of -19, to help
get a trace of a run-away process consuming high CPU.

eg.
$ nice -n -19 ./strace-brick.sh glusterfsd 50

will strace glusterfsd processes for 60 seconds which are consuming a
minimum of 50% CPU.
