After mariadb 10.5.18, mariadb fails to start if ssl cert parameters
are configured in the file but the certificates do not exist [1]. This
problem was fixed in puppetlabs-mysql 13.1.0[2] but we use older
versions (13.0.0 in stable/zed for example) in stable branch jobs.
CentOS Stream 9 has just bumped to mariadb-10.5.22 and this is breaking
all non-ssl jobs.
All releases <= Zed didn't use ssl in mariadb with p-o-i deployments
but puppetlabs-mysql set default values so we need to explicitly
undefine them.
