[darkn3rd]

There are some extra requirements needed for running tests. Suggestion to add tests/requirements.txt (below).
Documentation on testing requirements,

• docker cli
• go w/ $GOPATH
• dgraph git repo in $GOPATH/src/github.com/dgraph-io/

This is from pip freeze from virtualenv after installing:

• ./requirements.txt
• grpcio-tools
• coveralls
• docker-compose (needed later needed by dgraph/contrib/scripts/functions.sh)

I updated the requirements file in #140

I also updated the README to include info on the Dgraph requirement and go in #137

I'll update the readme again to include info on docker.
