Add new neutron port when TOR is disconnected and verify datapath is established after TOR connects back.
TOpology: 1CSS-2TOR
Basic config: 1 neutron VM is connected to each of the CSS and TOR devices in same network. L2gateway is configured towards both TORs.
Test Steps:
==========
>Nova delete Vm instance on CSS when both TORs are connected.->Corresponding entry is removed in remote ucast table in both the TORS and same in config DS for topology is seem.
->Disconnect one TOR
>Nova boot the VM on same neutron port.->The mac entry for VM in CSS is added in the remote ucast table for connected TOR and also in config DS for that node.
>Connect the first TOR(not clean restart)->The mac is added twice in the TOR in upper and lower cases as below

fa:16:3e:c9:ee:db is the mac of the neutron VM connected to CSS.
Solution :
While installing/creating RemoteUcastMacs convert the Mac to LowerCase such that duplicate entry will not get added again.
