* Update plugins/replication from branch 'stable-3.4'
  to 44171b65a0c1c390764cdd045aff1cd138c4b802
  - Ensure states are updated for canceled replication tasks
    
    When using 'replication start --wait' we need
    ReplicationState.waitForReplication() to return when the task we're
    waiting on has been canceled, either through an admin action or because
    the replication distributor determined another node already completed
    it.
    
    Add a couple tests for PushAll that confirm this behavior was previously
    broken and is fixed now.
