reconnects the locator to a restarting DistributedSystem. If quorum checks are enabled this
will start peer location services before a distributed system is available if the quorum check
succeeds. It will then wait for the system to finish reconnecting before returning. If quorum
checks are not being done this merely waits for the distributed system to reconnect and then
starts location services.

@return true if able to reconnect the locator to the new distributed system
