Rebase

Change to use alpine linux, much small base image size.
 + Change Maintainer to Label http://stackoverflow.com/a/39767934/1432051
 + run through dockfmt https://github.com/jessfraz/dockfmt

Split up build so dependencies can be cached.
However not sure if this is ideal from a security perspective.
