Update host_vars and sync-to-review-test playbook

The host is review-test.opendev.org, so hostvars for
review-test.openstack.org are not so much going to do anything.

It's easier if we just ssh as root from review to gerrit2
on review-test.

review-test needs to be in letsencrypt group and have a
handler.

We need to install mysql - it's on the existing review
servers but not in ansible, it's just left over from
puppet.

The db credentials are in /root/.gerrit_db.cnf
