a couple of comments on the run unit tests thru docker script to simplify.

[bwagner5]

instead of using alpine and installing dependencies, you can use the golang:1 docker container which already has go, git, and make installed.

[bwagner5]

I think the default workflow would be to run the unit tests and discard the container. Maybe change "recreate" to "preserve" instead which would effectively remove the --rm from the command below.

docker run -it --rm -e GOPROXY=direct --volume "$project_root_dir:$work_dir" --workdir "$work_dir" --name "$container_name" golang:1

Overall, looks very good! Going to go ahead and merge. We'll do some cleanup and polishing in smaller PRs.

I'm getting the following error since upgrading from 0.8.0 to 0.9.2. Seems potentially related to this PR. I have not set that value.
