Added test for snoop command to check for the initial handshake messages
when a bridge connects to a controller via 'unix' connection method.
Signed-off-by: Ashish Varma
---
v2-v3:
Moved 'on_exit kill" command before the start of the command to avoid the race
condition between start of the process and registering to have it killed on
interrupt.
Removed deletion of snoopbr0.txt to debug any failure.
Cleaner shell re-direct.
