class DomainTopologyManagerEventHandler extends UnsignedProtocolEventHandler with FlagCloseable with NamedLogging
When a new member joins, they send register topology requests to the Topology Manager via the sequencer. This handler takes care of the IDM handling these requests and sending the response back via the sequencer while also supporting crashes and making sure the response is sent at least once.
