  - Merge "Update VPN event strings for the IKE lib update"
  - Update VPN event strings for the IKE lib update
    
    With a recent update, the IKEv2 library exposed the internal
    errors happening on the link. This had us realize one error
    code was a little bit ill-named and the other can't be exposed
    because the system doesn't know about it happening.
    
    Update the name of the events for this.
