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.

+The roadwarriors <b>carol</b> and <b>dave</b> set up a connection each to gateway <b>moon</b>.
+At the outset the gateway authenticates itself to the clients by sending an IKEv2
+<b>RSA signature</b> accompanied by a certificate.
+<b>carol</b> and <b>dave</b> then set up an <b>EAP-TTLS</b> tunnel each via <b>moon</b> to
+the FreeRADIUS server <b>alice</b> authenticated by an X.509 AAA certificate.
+The strong EAP-TTLS tunnel protects the ensuing weak client authentication based on <b>EAP-MD5</b>.
+<b>carol</b> presents the correct MD5 password and succeeds whereas <b>dave</b> chooses the
+wrong password and fails.
