Subject: Enable TLS in the internal network for aodh

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

This, in turn should also configure a command that should be ran when
the certificate is refreshed (which requires the service to be
restarted).

 #
 # === Parameters
 #
+# [*aodh_network*]
+#   (Optional) The network name where the aodh endpoint is listening on.
+#   This is set by t-h-t.
+#   Defaults to hiera('aodh_api_network', undef)
+#
+# [*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).
+#
 # [*step*]
 #   (Optional) The current step in deployment. See tripleo-heat-templates
 #   for more details.
