nat: Send a IPA PING down the stream and wait for the pong.

We will send a ping every 20 seconds and if we have no pong
within 5 seconds we will close down the BSC connection and
wait for a reconnect. We will start this after having
authenticated the BSC and we stop the timer when destructing
the BSC connection.
