Stabilize control-node graceful-restart unit tests

o Checking that peers do not flip after simulating a cold-reboot is not consistent
-- If peer tries to send a message and get a RST back, then it would cause
its session to flip. Hence such a check must be done asap once the peer is
brought down on one side.

o Do not start SandeshServer by default. It hangs during TearDown() sometimes

Do not bring up peers when GR process is under progress

Peer sessions are not allowed to come up when GR is in progress. Once the state
enters GR_TIMER_WAIT or LLGR_TIMER_WAIT, then the sessions are allowed to come
up. However, it can so happen that when the peers are about to come up and
become established, the GR timers fire.. In this case, we do not want the peers
to come up to keep the design simple.

In such a rare scenario (which was exposed in some of the GR unit tests), flip
the peer gracefully.

It is to be noted in the normal GR state machine, most of the time is spent
in GR_TIMER_WAIT/LLGR_TIMER_WAIT states, which in the order of several minutes.
Hence it is not a common occurance for a peer session to come up at exactly the
same time as when the GR timers expire.

Tests marked as flaky still need to be monitored before unmarking some of them
if not all..
