For single-threaded replication it is linked from the RLI, for parallel
replication it is linked into each event group being executed in parallel.
In single-threaded replication, there will be one global rpl_group_info and
one global Relay_log_info per master connection. They will be linked
together.
In parallel replication, there will be one rpl_group_info object for
