    Check for available networks for a role

    For network isolation, we specifcy available networks for role.
    Therefore, there is no point in creating noop network resources for
    networks that are not available/connected. This results in redundant
    host entries for not available networks on overcloud nodes.

    If a network is not available for a role we don't need to create
    those extra noop resources.

    For Undercloud/Standalone role we keep all networks in roles data
    as the default ServiceNetMap specifies non ctlplane networks though
    they map to ctlplane.
