Previously, Nova would always bind to '0.0.0.0'.
This change allows users to specify the IP address for
binding Nova API endpoints.
The change introduces the api_bind_address parameter within the
openstack::nova::controller class and the nova_bind_address in
the openstack::controller class. nova_bind_address was used for
consistency with other OpenStack services.
Defaults to '0.0.0.0' for backwards compatibility and to have all
Nova API's bind to all IP addresses.
