testing: Add scenarios that use XFRM interfaces

The network namespace scenario requires a kernel patch in 4.19 and 4.20
kernels (the fix is included in 5.0 kernels).

+This scenario demonstrates a property of <b>XFRM interfaces</b> that allows
+moving them into network namespaces while retaining access to IPsec SAs and
+policies in the original namespace. This enables an IKE daemon in one namespace
+to provide IPsec tunnels for processes in other namespaces without having to
+give them access to the keys and IKE credentials.
+<p/>
+The gateways use <b>route-based forwarding</b> with <b>XFRM interfaces</b>, with
+firewall rules to allow traffic to pass. The IPsec traffic selector used is
+0.0.0.0/0, however, specific routing is achieved with routes on the XFRM
+interfaces.  The IKE daemon does not install routes for CHILD_SAs with outbound
+interface ID, so static routes are installed for the target subnets.
+<p/>
+The XFRM interface on gateway <b>moon</b> is moved into a new network namespace
+from which a ping is sent to client <b>bob</b>. It is then moved back out and
+<b>alice</b> sends another ping to <b>bob</b> to test if that works too.
+<p/>
+Gateway <b>sun</b> dynamically creates the XFRM interface via updown script
+using the passed unique generated interface ID.
+<p/>
+Note that the dropped packet seen on the <b>XFRM interface</b> on <b>moon</b>
+is an IPv6 Router Solicitation (NDP) sent from that namespace, which doesn't
+match the IPsec policy.
