Introduce Healthcheck

[JoeSSS]

We need something that will decide whether simulator is ready to work or not, rather than retry 70-80 times to get the command done

[BasThomas]

This should also verify that, in case there are changes within this folder, you should add an entry to the changelog as well.

[BasThomas]

Can you explain what you expect from this? I've opened #146 adding CI, which would enable us to do this.

[JoeSSS]

This is about checking if Simulator, app and web server are up and running. So the launcher will not try to work with it using hardcoded timeouts

[BasThomas]

Ah, so it's within the app; it has nothing to do with CI?

[JoeSSS]

yeah
