Submitting Validation requests can block ANTI_ENTROPY stage

    Details

      Description

       RepairMessages are handled on Stage.ANTI_ENTROPY, which has a thread pool with core/max capacity of one, ie. we can only process one message at a time. 
       
      Scheduling validation compactions may however block the stage completely, by blocking on CompactionManager's ValidationExecutor while submitting a new validation compaction, in cases where there are already more validations running than can be executed in parallel.
