Adds a new poll extension to provide get_hardware_info and get_node_info interfaces. get_hardware_info will be used for node validation by ironic deploy drivers. get_node_info will be used for sending lookup data to IPA. standalone mode is assumed as debug only, but it's not the case considering the poll mode will be introduced, slightly updates the description, also prevents the mdns lookup when standalone is true.
