    cluster/tier: break out of iterating query file once cycle time ends
    
    When iterating the query file during migration, tiering should
    break out of the loop once cycle time completes. Otherwise it
    may be possible to stay in the loop for a long time. If that
    happens updates to files will become stale and have not impact
    migration.
