Add healthcheck

Adds a healthcheck.

Just out of interest: Did you experience any problems with the service not being responsive? I mean it probably won't hurt to have a healthcheck in there, but in case you've experienced some actual issues I would prefer do add some debug logging to track the issue down. :)

This is not a question of responsiveness but of completeness 😉 no problems seen so far.

You will be able to see the state using docker ps or some monitoring systems.

CONTAINER ID        IMAGE                                    COMMAND                  CREATED             STATUS                    PORTS                                                              NAMES
3b93a07859d1        bbernhard/signal-cli-rest-api:latest     "/entrypoint.sh"         13 minutes ago      Up 13 minutes (healthy)   8080/tcp                    

e.g. Up 13 minutes (healthy).

Oh, didn't know that. Ok, then let's merge the change ;-). Thanks!

I would even provide a /health endpoint for this use case which gets excluded for the logging, so it won't spam the logs.
