openstrongswan: get the PDP type out of the IKE_AUTH/CFG_REQUEST

Description
According to 33.402 / Section 8.2.2
The UE sends the "Configuration Payload, Sec. associations, Traffic selectors, APN info" in the first IKE_Auth Request.
Strongswan doesn't care. It only takes the APN and UE Identity from it. But nothing else.
1) Use a real phone to see the request and get the wireshark decode table
2) Find out when those information is available to collect it with the strongswan code (osmo-epdg plugin).
3) Send the correct type in SendAuthInfo and/or Location Update Request towards the osmo-epdg (erlang)
