      wl#3584 GTID
      
      relaxing conditions for HB info validation.
      Master can skip transactions that slave already got and this
      fact is never reported so the vanilla GTID-less logics
      fail because implicitly MI.pos should include the size of the
      skipped transactions.
      
      Until HB does not carry the skipped size validation only 
      condiders monotonicity, i.e
      HB.pos >= MI.pos when gtid_mode is ON.
