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.

+A connection between the subnets behind the gateways <b>moon</b> and <b>sun</b> is set up.
+The authentication is based on <b>X.509 certificates</b>. Upon the successful
+establishment of the IPsec tunnel, <b>leftfirewall=yes</b> automatically
+inserts iptables-based firewall rules that let pass the tunneled traffic.
+After a while the CHILD_SA is rekeyed by <b>moon</b> (after a deliberately short
+time in this test scenario).
+In order to test both tunnel and firewall after the rekeying, client <b>alice</b>
+behind gateway <b>moon</b> pings client <b>bob</b> located behind gateway <b>sun</b>
+twice, once right after the rekeying and once after the old inbound SA has been
+deleted.
