testing: Reorganizing IKEv1 and IKEv2 examples

For documentation purposes the new folders ikev1-algs, ikev2-algs, ikev1-multi-ca and ikev2-multi-ca have been created. Most of the test cases have now been converted to the vici interface. The remaining legacy stroke scenarios yet to be converted have been put into the ikev2-stroke-bye folder. For documentation purposes some legacy stroke scenarios will be kept in the ikev1-stroke, ikev2-stroke and ipv6-stroke folders.

+By setting <b>left=%any</b> this scenario tests the ability of the IKEv2 daemon
+to automatically determine its own IP address of an IPsec SA to be established.
+This is achieved by finding a route via the correct network interface to the remote IPsec peer.
+<p>
+The hosts <b>moon</b> and <b>bob</b> act as initiators by setting <b>auto=route</b>
+whereas the hosts <b>alice</b> and <b>sun</b> act as responders by setting <b>auto=add</b>.
+Pings from <b>moon</b> to <b>alice</b> and <b>sun</b> as well as a ping from <b>bob</b>
+to <b>sun</b> set up three compressed IPsec Transport Mode connections.

+The roadwarriors <b>carol</b> and <b>dave</b> set up a connection each to gateway <b>moon</b>
