    Description

      Common maintenance chores require restarting Solr instances.

      The process of a shutdown becomes a whole lot more reliable if we can proactively move any leadership roles off of the Solr instance we are going to shut down. The leadership election process then runs immediately.

      I am not sure what the semantics should be (either accomplishes the goal but one of these might be best):

      • A call to tell a core to give up leadership (thus the next replica is chosen)
      • A call to specify which core should become the leader
