This optionally enables TLS for Panko API in the internal network.
If internal TLS is enabled, each node that is serving the Panko API
service will use certmonger to request its certificate.

 #
 # === Parameters
 #
+# [*certificates_specs*]
+#   (Optional) The specifications to give to certmonger for the certificate(s)
+#   it will create.
+#   Example with hiera:
+#     apache_certificates_specs:
+#       httpd-internal_api:
+#         hostname: <overcloud controller fqdn>
+#         service_certificate: <service certificate path>
+#         service_key: <service key path>
+#         principal: "haproxy/<overcloud controller fqdn>"
+#   Defaults to hiera('apache_certificate_specs', {}).
+#
+# [*enable_internal_tls*]
+#   (Optional) Whether TLS in the internal network is enabled or not.
+#   Defaults to hiera('enable_internal_tls', false)
+#
+# [*generate_service_certificates*]
+#   (Optional) Whether or not certmonger will generate certificates for
+#   HAProxy. This could be as many as specified by the $certificates_specs
+#   variable.
+#   Note that this doesn't configure the certificates in haproxy, it merely
+#   creates the certificates.
+#   Defaults to hiera('generate_service_certificate', false).
+#
+# [*panko_network*]
+#   (Optional) The network name where the panko endpoint is listening on.
+#   This is set by t-h-t.
+#   Defaults to hiera('panko_api_network', undef)
+#
 # [*step*]
 #   (Optional) The current step in deployment. See tripleo-heat-templates
 #   for more details.
 #   Defaults to hiera('step')
 #
