[erlang-questions] relx: how to use system erlang, not embed from my computer?

Yea, we were doing the same at Heroku. A docker image that built the
release and uploaded to S3 so we could deploy.

It is a decent flow, but now I have just travis-ci doing the build,
after tests pass, and uploading to S3. Which works nicely.

I intend to document different deployment and upgrade strategies on
rebar3 and relx websites eventually.
