          Description

          In GTID mode, the current slave pos is stored crash-safe in
          mysql.gtid_slave_pos. There is no need to update the relay-log.info file after
          every event group, which is not crash-safe anyway and costs performance
          (write(2) syscall for every transaction).

          Especially with parallel replication, the update of relay-log.info could
          start to hurt.

          It could perhaps be an option, in case some existing monitoring solutions want
          to read the file from outside the server rather than use SHOW SLAVE STATUS.

                I believe this was done as part of MDEV-4506.
