    mysql: fix root password update for containerized mysql

    Since the mysql service has been containerized, we lost the ability
    to update the root password during a stack update.

    When the mysql root password in hiera differs from the one currently
    set in the mysql DB, connect to the DB with password from .my.cnf and
    update credentials of the root user before the puppet mysql module
    tries to access the database. Also update other root DB users.
