Is your feature request related to a problem? Please describe.

• As a first time committer, trying to compile it on my development machine was quite tedious process . A development docker file will help quickly onboard anyone who wants to get a taste of development. Example of docker file : https://github.com/shashanksingh/rethinkdb/blob/next/Dockerfile

Describe the solution you'd like Example of docker file : https://github.com/shashanksingh/rethinkdb/blob/next/Dockerfile

Describe alternatives you've considered

1. Building locally, obviously long term this would be best solution .
