An OE connection only covering tcp port 7 to east. This one is
configured for both incoming and outgoing port 7. This tests if the
priorities of protoport OE connections get the right values.

(we use 7 so we can echo something and get closed connection)

Compared to newoe-18-poc-cop-port-7-both, the order of the
clear-or-private policies on east is reversed. This causes east to
initiately pick the wrong clear-or-private group to instantiate, and
it needs to switch during IKE_AUTH
