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.

+This scenario tests <b>repeated authentication</b> according to RFC 4478.
+The initiator <b>carol</b> sets a short <b>ikelifetime=20m</b> but the responder
+<b>moon</b> defining a much larger <b>ikelifetime=30s</b> proposes this
+value via an AUTH_LIFETIME notification to the initiator. The initiator
+ignores this notification and schedules the IKE reauthentication within
+the shorter interval of 30s. A ping from <b>carol</b> to client <b>alice</b>
+hiding in the subnet behind <b>moon</b> tests if the CHILD_SA has been
+inherited by the new IKE_SA.
