[kudu-CR] KUDU-418 (part 1): enforce that we don't support changing TS hosts/ports

["Todd Lipcon (Code Review)" <ge...@cloudera.org>]

Hello Kudu Jenkins,

I'd like you to reexamine a change.  Please visit

KUDU-418 (part 1): enforce that we don't support changing TS hosts/ports

This adds a check in the master that attempts to reject tablet servers which
have changed host/port. We don't currently support this, so allowing them to
register currently just ends up hitting other more hard-to-diagnose issues
later on.

This check will end up being rolled back when we actually implement a proper
fix for KUDU-418. In the meantime, this would have helped me troubleshoot some
issues with client-test where we hit this issue.
