Fix deprecated options from MySQL 8.2 (#662)
* Fix show master status for MySQL 8.2+ * Fix mysqldump option form --master-data to --source-data * Fix incompatibility between mysqldump 8.0 and MySQL 8.4 Installing the same version between the client and the server makes sense anyway. The incompatibility arise when you use mysqldump with --source-data. The the tool tries to perform a SHOW MASTER STATUS which is deprecated in MySQL 8.2+. * Fix missing condition * Fix unit tests * Add a query resolver depending on implementation and version * Sanity * Fix SHOW REPLICA STATUS queries * Fix mariadb's SHOW REPLICA HOSTS query * Fix CHANGE MASTER for MySQL 8.0.23+ * Fix integration test for CHANGE MASTER * Fix integration test for CHANGE MASTER * Fix replication queries for MySQL 8.0.23+ and 8.4+ * Revert file edited by mistake * Enhance tests format
