Support read from specific MySQL Binlog gtid

Support read from specific MySQL Binlog gtid.
When reading a highly available MySQL Cluster, a master-slave switch or IP drift occurs and the checkpoint is not updated in a timely way, resulting in a failure to start reading from the checkpoint file due to a change in GTIDs.Since our checkpoints are spaced far apart, this is likely to affect us.
We added the GTID field in the checkpoint file to facilitate our clients to get the accurate GTID.
