This is an IKEv2, insist, test using X509 certs on the initiator
(road), and on the responder(east). It has two connections, IPv4 and
IPv6. IPv4 has leftsubnets and IPv6 has a subnet and rekey timers are
short.

Though the rekey timers are short, automatic runs don't wait that long.
If you want to rekey correctly run the test manually (with patience).
