pre-start is no longer needed if we mount the certs in /etc/pki

The problem with /var/lib/pgsql/data/userdata is if this is a new install,
initalizing the database will fail because the userdata directory is not
empty and it is expected to be empty.  Since the postgres configs are always
mounted on the pod we need the certs to be in a predictable location.
