TLS can be used to encrypt and authenticate the connection with
OpenStack endpoints. This patch provides the necessary
parameters and changes the resulting service configurations to
enable TLS for the Kolla deployed OpenStack cloud.
The new input parameters are:
kolla_enable_tls_external: "yes" or "no" (default is "no")
kolla_external_fqdn_cert: "/etc/kolla/certificates/haproxy.pem"
kolla_external_fqdn_cacert: "/etc/kolla/certificates/haproxy-ca.crt"
Implements: blueprint kolla-ssl
