MDEV-27697 slave must recognize incomplete replication event group

Browse Source 
In cases of a faulty master or an incorrect binlog event producer, that slave is working with,
sends an incomplete group of events slave must react with an error to not to log
into the relay-log any new events that do not belong to the incomplete group.

Fixed with extending received event properties check when slave connects to master
in gtid mode.
Specifically for the event that can be a part of a group its relay-logging is
permitted only when its position within the group is validated.
Otherwise slave IO thread stops with ER_SLAVE_RELAY_LOG_WRITE_FAILURE.
