Disconnect VPN when the underlying network is lost
This commit mainly does 2 things:
1. Reset IKE state and disconnect VPN network when the underlying
network is lost.
- It can prevent giving a false sense of connectivity to the
app when the VPN is not working due to losing the underlying
network, update the state of VPN is needed.
2. Update the exception of handleSessionLost() from null to
IkeNetworkLostException.
- It fixes the problem that the ERROR_CODE_NETWORK_LOST will
not be sent when the underlying network is lost.
