[kolla-ansible] haproxy tls key location

Hi All,

Reading through https://docs.openstack.org/kolla-ansible/latest/admin/tls.html and global.yml / passwords.yml in my deploy I see configuration for certificates but not where to set the key (though there is a key location configuration for backend tls in globals.yml).

Unsurprisingly when I put the certs where they are expected and enable TLS the haproxy containers fail because they don't have a key.

What am I missing here?

Thanks, -Jon
