[PATCH-next v2 11/25] lnst.Devices.Device: add ips_filter method

From: Ondrej Lichtner <olichtne(a)redhat.com&gt; The method retuns a list of ip addresses that match the provided selectors. The selectors are key=value pairs where 'key' is some attribute of the ipaddress object, if an ipaddress object matches all the selectors it is added to the return list of the method.
