Comment 2 for bug 1706118

As noted in IRC, it sounds like another variant of bug 1673613 which was fixed in Ocata 15.0.5:

https://docs.openstack.org/releasenotes/nova/ocata.html#id1

Which is what's being used here, so probably another case we need to handle in this code:

https://github.com/openstack/nova/blob/321f426c30f8f4f6e3dcafbbc7e5d87560b58c82/nova/cmd/manage.py#L1190-L1204

And that's parsed from the nova (cell1) database connection string, which from above is this:

"mysql+pymysql://nova:my_password@my_ip/nova?charset=utf8&ssl_ca=/etc/nova/tls/mysql/ca-cert.pem&ssl_cert=/etc/nova/tls/mysql/server-cert.pem&ssl_key=/etc/nova/tls/mysql/server-key.pem"
