[developer experience] Add docker-compose file for simpler local development

[hydrosquall]

This PR adds a docker-compose script that can run Redis and MongoDb inside a docker container, for more convenient local development.

This is my first pass at https://github.com/enjalot/blockbuilder-search/issues/74 .

How to Test

• Assuming you have homebrew, install docker-compose and docker.

   brew cask install docker

Then, clone blockbuilder and perform the basic setup.

# Terminal
yarn
yarn buildWatch

# Terminal 2
docker-compose up 
# When done, remove networks with with docker-compose down

# Terminal 3
node server.js

The application will be available on localhost:8889!

Process Notes

• I tried setting up a custom bridge network using the docker docs, passing in a custom redis.conf to bind redis to all ports instead of just localhost, and linking the services using the link key in docker-compose, with no luck - the mongo_client code is unable to bind to redis. I'm not sure why yet. I do know redis was running correctly because I could still connect to it via redis-commander.

• Happily, this seems to work just fine running the node server on your laptop directly, so this docker compose setup already is preferable to me manually spinning up mongo and redis.

• I realized in working this that I suspect that running all this on a local machine is unnecessary if someone wants to just make frontend changes, so I am going to try to come up with an alternate workflow specifically for hacking on the blockbuilder-search page.

Great! I was thinking of accompanying this change with an update to the wiki setup instructions for local development or in the readme for this project directly - what do you think?

@hydrosquall yes, please document it somehow. let me look, but I think that the wiki is the right place for this repo

history: @enjalot prefers docs in the wiki, @micahstubbs prefers docs in markdown files under version control. because of this history, different repos in the blockbuilder-verse have docs in different places.

ok @hydrosquall please do add a section here that describes how to optionally run redis and mongodb in a docker container https://github.com/enjalot/blockbuilder/wiki/Development#setting-up-databases
