Bug Description

For segment health check for transparent SI, the HC packets are dropped by the VMs intermittently.

Naveen debugged it to find that the packet's dst mac is set to vrrp mac, and as its already learnt, packets are dropped on the left interface. And after arp timeout, maybe packets go through.

Do not use vrouter mac in the segment health check packet

Hard coding to use the same MAC that we use in other traffic to transparent
service instance (02:00:00:00:00:01 while sending on left and 02:00:00:00:00:02
while sending on right interfaces).

Change the MAC used for segment health check packets

Using vrouter mac as destination MAC could result in packets getting
dropped in the transaparent SI, as it is learnt on different interfaces
while receiving ARP packets. Changing to use new source and destination
MACs for these packets and add bridge entries for these.
