Have Documentation for easy docker setup in dev environment

[kshitijrajsharma]

This issue is to create documentation and integration of all API features with docker . Which will make target user easy when there is task queue system so that they don't need to setup and start other services manually

I just encountered an issue while trying to setup docker on my PC.

• The first issue is that the docker build \Docker is throwing error ( see SS).
  

What fixed it for me is moving the Docker file to the root directory and making some re-arrangements.

I can already see that you are working on this in the celery branch. Welldone!
