MT#65243 Plugin::NGCP::Redis handle 'active-replica' state

* Catalyst::Plugin::NGCP::Redis::_wait_for_master_role() only
  expected the 'master' value to be considered as OK, whereas
  with Redis/KeyDB the value can be also 'active-replica'.
  Therefore, consider both 'master' and 'active-replica' values
  as OK.
