Description:
Document describes "START REPLICA is legitimacy, START SLAVE is its alias".

> From MySQL 8.0.22, START SLAVE is deprecated and the alias START REPLICA should be used instead

Therefore, change "START SLAVE" to "START REPLICA" in Error/Warning messages.

How to repeat:
$ grep -r 'START SLAVE' include/

Just one example, 

mysql80 14> CHANGE REPLICATION SOURCE TO source_host = '127.0.0.1', source_user = 'dummy', source_password = 'dummy';
Query OK, 0 rows affected, 2 warnings (0.06 sec)

mysql80 14> SHOW WARNINGS;
