BUG#36625: Please remove the rpl_probe and rpl_parse features from the server

Problem 1: BUG#36625: rpl_redirect doesn't do anything useful. It tests an
obsolete feature that was never fully implemented.
Fix 1: Remove rpl_redirect.
Problem 2: rpl_innodb_bug28430 and rpl_flushlog_loop are disabled despite the
bugs for which they were disabled have been fixed.
Fix 2: Re-enable rpl_innodb_bug28430 and rpl_flushlog_loop.

mysql-test/suite/rpl/t/disabled.def:
  Re-enabled tests.
mysql-test/suite/rpl/t/rpl_redirect.test:
