Microservices fail to start without Stackdriver variables in .env file.

I tried getting this project running from the README. Ran into two problems:

1: Had to go get go-bindata

go get -u github.com/jteeuwen/go-bindata/...

2: I then got the following error on make run: Couldn't find env file

3: I added a blank .env file. I don't want to play with Tracing using Google Stackdriver at this time.

❯ make run ...

docker-compose up

Creating gomicroservices_geo_1

So it appears that this project won't run without setting up Google Stackdriver?
