NFR: Keep Alive - Ping Pong

[ruudboon]

With unstable connections it sometimes happens that the connection is reset or you find out too late that the connection isn't reachable. I'm looking for a solution that actively checks the connection with the host and automatically tries to reconnect.

We builded a small prototype to demonstrate a solution.
It's based on a message that is delivered every second with the Scipting Name "keepalive". After the first message we start a timeout of 2 seconds. If a new message comes in we reset the timer.

When we break the connection to the host and the timeout expires after 2 seconds we trigger a disconnect and connect to reestablish the connection.

I wouldn't mind delivering a proper pull request but would like some directions how to implement this in a proper way.
