feature/geo-rep: Fix to retain pause state of gsyncd on restart.
A new gsyncd options '--pause-on-start' is introduced. When node
reboots, if the status is paused, gsyncd is started with this
option. After gsyncd spawns worker and agent, worker will send
SIGSTOP to negative pid of monitor to enter pause mode.
