Remove all useless scapy WARNING: on import from scapy
Just delay a whee bit in SSH agent before closing channel/session.
For some reason, there seems to be unread data in the tcp queue.
When closed quickly ends up RST'ing the tcp/onos-karaf server side session.
This causes a bogus "Connection reset by peer" exception in the ONOS log for every cli session established to ONOS from cord-tester
