Tenant VMs lose connectivity for more than 4 Mins during vmotion

[Priyanka J]

Ping should recover with few secs after vmotion/migration, but here it losts for more than 4 mins and recovers after that.

This bug is blocker to validate ovsvapp sanity testcases for Vmotion.

Sequence to recreate this bug,

1. Deploy CS 10.1 with ESX computes in VLAN environment .
2. Create a VM in VLAN network
3. Assign FIP to the VM
4. Add a ICMP rule to allow ping traffic
5. Ping the VM using FIP , its successful .
6. Now Migrate the VM to another host
7. Ping connectivity of the VM is lost for more than 4 Mins.
