Remove mariadb-server packages from the host
During updates/upgrades, installing mariadb-server on the
host may impact the behaviour of containerized mysql.
During a FFU if mariadb-server is upgraded, it may happen
that the rpm scriptlets fail to start mariadb server and
leave a crash log behind (tc.log). This prevents the
regular online upgrade from happening.
During an upgrade, mariadb-server used to be force-upgraded
in the mysql service for historical reasons. It's not
necessary since mysql is containerized and can trigger
the same crash as explained above.
During a minor update, the same reasoning can apply if
RHEL channel ships a new mariadb-server rpm as scriptlets
will probably leave a crash behind as well.
Make sure mariadb-server is never installed, while
keeping mariadb CLI if already present on the host, to
avoid operational impacts.
