    Enable policy rule management in nova-compute

    There are some features in nova-compute which validate policy rules.
    For example when connecting an instance to an external network,
    nova-compute checks ``network:attach_external_network`` to determine
    whether the operation is permitted.

    This change migrates definition of nova::policy hieradata from nova-api
    to nova-base so that the hieradata can be used by both nova-api and
    nova-compute.
