Implement external IP reassignment from a failed BGW instance to a substitute BGW instance, in AWS.
Context of new functionality
When L2GW-Agent disconnects from an active OVSDB and selects a substitute (refer to #35 ), it will call a hook point (refer to #36 ), which allows additional steps to be taken in order to ensure successful failover of the BGW.
In this task, we will implement reassignment of the external IP of the failed BGW, to which external BGW forward traffic from remote MACs.
