[PATCH-next 6/9] lnst.Common.IpAddress: add flags attribute

From: Ondrej Lichtner <olichtne(a)redhat.com&gt;

This optional attribute can store flags as provided by the kernel, this
can be used for example for checking if an address is tentative as is
the case for IPv6 addresses that haven't been DAD checked yet.
