Ansible free dockerfile

[zubairshakoorarbisoft]

ISSUE: #303
This PR is part of effort aimed at removing Ansible based configurations and replacing them with Dockerfile. Currently Devstack Docker images are built using Ansible based configurations in the configurations repository. Through this effort we will make sure that the Repo has its own Dockerfile which has all the necessary configurations to setup small production and dev environments.

Steps to run this Image with Devstack:

Build the Image locally first using the target dev i.e. docker build -t image-name-of-choice --target dev .
After the image is built successfully go to the docker compose file of devstack and replace the existing insights image with the one that you built without changing any other configurations there.
Run make dev.up.edx_notes_api in the terminal while in the devstack directory.
