Create integrated work environment with Docker

[plonajakub]

In the past week, we encountered some troubles with setting up the necessary dependencies required by Renode and Zephyr. Future expectations are to automate the testing process of our custom voice-assistant app. Therefore it will be helpful to have an integrated docker image not only capable of running simulations but also building our app and testing it.

The docker image will be based on existing renode image.

The goal is to have a docker image with an integrated work environment for our project.

Responsible for this task is @szymon-filipiak.

As for now, I'm creating the image with the demo app. Then I will create a docker-compose file, that would check out the newest version of code from local files and use it to build and deploy our app.

Feel free to comment if you have any advice, objection or a different approach for this because I lack experience in DevOps stuff.
