Implement GTID based replication

[altmannmarcelo]

Description

When available we should be using GTID instead of Binary log file and position as it will make failover easier.
A few things to consider:

• Since we have per table binlog position and we have selective table replication, we need to ensure that we don't create GTID gaps for events that we skip.
• MySQL added support for GTID Tags, so the layout might look uuid:seq_id or uuid:tag:seq_id - we should be able to store both
• MariaDB layout is also different, we should check if we can easily implement this and comply with both formats
• Once this is done, we should register as a replica using auto_position=1 (GTID)
