A number of new settings are required for glance, cinder
and keystone to be installable when the tls-proxy
service is enabled.
For cinder a new public_endpoint option was added and this
needs to be set to the secure port.
Keystone needs the admin_endpoint and public_endpoints
defined otherwise during discovery the default,
non-secure versions, will be returned.
The keystone authtoken identity_uri was set at its default value
in the glance registry and API configuration files.
