strongswan config being generated with ike SA lifetime set to value of ipsec SA lifetime
0%
Description
Connection entries in /var/etc/ipsec/ipsec.conf are being generated with ikelifetime set to 3600s when the GUI shows the phase 1 lifetime being 28800s.
vpn_ipsec_configure in /etc/inc/vpn.inc writes a variable called lifeline to the file for each phase 2 entry. It first sets this variable to the lifetime value of the phase 1 entry and then overwrites that with the value of the phase 2 entry.
There are 2 separate parameters for this supported by strongswan. ikelifetime and lifetime. Setting the ike values as ikelifetime and the IPsec values as lifetime in the connection should work.

I think this change might have caused an issue. On August snapshots, i'm not able to negotiate IKE with another device as the IKE lifetime is transmitted as 0 seconds, which is invalid. This is confirmed by the logs on the remote device and via a packet capture captured at a point between pfSense and the remote device. I've put more details over on the snapshots forum at https://forum.pfsense.org/index.php?topic=80060.0

I believe it was actually this change that caused the lifetime to be set to 0. https://github.com/pfsense/pfsense/commit/f088b8cd6a0f7a9611da41477a565e9c4b502080
If I manually set rekey = yes and restart ipsec, i see the correct lifetime being sent when the ikev1 SA is established.
