extras: kill processes gracefully

Currently all of brick, gsyncd and other glustershd services/processes
are killed without checking for ongoing tasks such as geo-rep,
self-heal, rebalance and etc. which may lead to inconsistency after
the node is brought back.

This patch introduce an option '-g' which ensures whether all the
gluster processes are ready (not busy) to be terminated before we
executing 'kill' on them

Usage: ./extras/stop-all-gluster-processes.sh [-g] [-h]
    options:
    -g  Terminate in graceful mode
    -h  Show this message, then exit

 eg:
  1. ./extras/stop-all-gluster-processes.sh
  2. ./extras/stop-all-gluster-processes.sh -g

By default, this script executes in force mode, processes are killed
without checking for ongoing tasks, on specifying '-g' option this
script works in graceful mode, which returns exitcode if some of gluster
processes are busy in doing their jobs.

exitcodes include:
   0       No errors/Success
   64      Rebalance is in progress
   65      Self-Heal is in progress
   66      Tier daemon running on this node
   127     option not found
