Easy Debugging with docker compose

[danez]

This adds two files for debugging, on is the docker-compose config and the other is the config for a fake test datasource.

How to use it:

1. Install docker for your OS
2. In the project folder run docker-compose up
3. go to http://127.0.0.1:3000/ and login with admin:admin and test the meta query plugin.
4. When you are done just press Ctrl+C in the commandline where docker-compose was running.

The version in the docker-compose config is set to latest, but can be changed to any version down to 2.x

Not sure if you want to merge this, it just made it super easy for me to test different versions.

I'd appreciate if that would be available to everyone.
