IMPALA-9180 (part 3): Remove legacy backend port

The legacy Thrift based Impala internal service has been removed so
the backend port 22000 can be freed up.

This patch set flag be_port as a REMOVED_FLAG and all infrastructures
around it are cleaned up. StatestoreSubscriber::subscriber_id is set
as hostname + krpc_port.

Testing:
 - Passed the exhaustive test.
 - Did manually testing on a dev cluster, verified that CM with fixing
   work with new version of Impala, which set subscriber_id as hostname
   + krpc_port. Verified the subscriber_ids of Impalad in Statestore Web
   Server. The health check of Impala cluster on CM worked as expected.
 - Passed CDH L0 test on cdpd-master branch.
