MariaDB-11.4 added a default self-signed TLS cert. With this
in the cases where there is no secure password there will be a TLS
error. By setting the password, the connection can continue.
Adding the password is compatible with MySQL and equivalents.
Due to MariaDB diverging from MySQL, MariaDB-11.0+ containers
don't include mysql compatibility links and use mariadb as the
CLI. This has been there since MariaDB-10.4.
