Based on some comments from another issue, there was a mention of a Java implementation to access the internal server running in container. This may be a good approach to implementing healthchecks on the running container, as I'm seeing the server go silent after some time running.

This leads to the more pressing issue of needing some graceful shutdown in the entrypoint script. If there is a need to down the server, for now I'm needing to exec into rcon-cli and stopping the server there. With the default restart always this just starts the server right back up. Having code that traps the docker exit signaling and gracefully shutting down the server would be very helpful.

I'll try to see what I can come up with in PR's to get things started, but my other projects are requiring lots of time, so I don't actually play my servers, just watch them for other players running on my nodes.
