Feature/docker setup

[prageeth-peiris]

Hi,

I have done the docker integration for this valuable project. If someone wants to run this on kubernetes you can use the docker image I have created.

https://hub.docker.com/r/prageethatdocker/groveco_content_engine

Also just to run the project locally with docker you can run the command "docker-compose up" in the path where docker-compose.yml file exists. (This uses the docker image I have pushed to dockerhub and the offcial redis image. This is the easy way to run the project as you have no extra work!)

And you can also build your own docker image using the dockerfile I have created. Please remember I have changed lib versions in requirements.txt to to install libs using pip without problems. And you have to connect your own custom redis instance with your docker container in this scenario.

This setup has been tested on 11th Jan 2021 and it is running without no problems.

You can interact with API on 5000 port as exactly in documentation with this docker setup.
