BFDD: Add RTT to BFD IPV4 Echo packet processing
Add a send time into the BFD Echo packet. When the BFD Echo
packet is received back store time it took in usec. When
user issues a show bfd peer(s) command calculate and display
minimum, average, and max time it took for the BFD Echo packet
to be looped back.
