The external PKI role can generate a self signed CA and Intermediate
certificate, and then create a server certificate for haproxy if
no defaults are overridden.
The new openstack_pki_* settings allow an external self signed CA
to be used, but still create valid haproxy server certificates from
that external CA in an openstack-ansible deployment.
The original beheviour providing user supplied certificates in the
haproxy_user_ssl_* variables will still work, disabling the generation
of certificates but using the external PKI role to just install the
supplied certs and keys.
