Feature to use back-end in docker

[quillcraftsman]

Back-end place https://github.com/findsimilar/demo here.
This is python django drf project.
To easy start we can use IS_MOCK_RESPONSE=true to work with static data.
If we need local back-end we should clone back-end project and start server locally.
It's not comfortable (especially who doesn't know python)

That's why I propose to make feature to run back-end in docker and make possibility to connect from front-end
We have open source image on docker hub: https://hub.docker.com/r/findsimilar/demo, may be we can use this image.
