testing: Migrate MOBIKE tests to vici

Note that the mobike-nat test has been removed as it basically did the same as the mobike-virtual-ip-nat test. Instead, the mobike-nat-mapping scenario is added, which simulates a NAT router restart.

+The roadwarrior <b>alice</b> is sitting behind the NAT router <b>moon</b>.

+in the subnet behind. When the NAT router <b>moon</b> is restarted, the NAT

+The roadwarrior <b>alice</b> is sitting behind the router <b>moon</b> but
