> In the graceful shutdown,  we keep the member as active until it receives ReadyToShutdown
event. In between these state changes, member will become unavailable. So the LB needs to
aware of that, in order to avoid sending requests to a member which is going to graceful shutdown.
I think that if we introduce another state say Maintenance in the Topology, before the actual
shut down of the application inside the member takes place, then the LB will act upon the
Maintenance state and  remove the member from the active members list.
