Report GP session lifetime

OpenConnect doesn't have a mechanism to immediately stop trying to reconnect
after the session expires.

Server-forced session expiration "takes care of itself" when OpenConnect
tries to reconnect repeatedly and fails, though it might be useful to save
the expected expiration time somewhere to be able to report it in a more
user-friendly fashion.
