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.

+Using the <b>left|rightprotoport</b> selectors, two IPsec tunnels 
+between the roadwarrior <b>carol</b> and the gateway <b>moon</b> are
+defined. The first IPsec SA is restricted to ICMP packets and the second
+covers TCP-based SSH connections. The established tunnels are tested
+by <b>carol</b> by first pinging <b>alice</b> behind <b>moon</b> and
+then setting up an SSH session to the same client.
