Motivation
Right now, topic creation tries to create replicator and if that fails due to any reason (one of the reasons blank TLS URL cluster URL) then broker doesn't catch exception, doesn't log error and topic loading gets stuck.
Modification
Handle replicator creation failure so, broker can load the topic again and broker can log the message.
