watchfrr: Extend ignore option to daemon being killed

Browse Source 
When testing GR features, it is desired to kill bgp
(or really any daemon )and not immediately have bgp start up again.
Modify the code to not attempt to restart the daemon
by hand to let us developers work when the `watchfrr ignore XXX`
command is issued.

Testing:
watchfrr ignore bgpd
kill -9 bgpd
start bgp by `/usr/lib/frr/watchfrr.sh start bgpd` at some point in time
in the future

leaf-1# show watchfrr
watchfrr global phase: Idle
