Remove local docker requirement for developer workflow

[jwmatthews]

Allow a developer to build/test/iterate on APB development to a remote cluster without requiring docker usage on their local machine.

@dymurray added a documentation workaround that will not require local docker access here
#257

[dymurray]

Please let me know if the above workaround allows you to get the image bootstrapped from the broker without Docker.

@dymurray 's solution is great.

Just to throw out another option that may work for some people, you should be able to build locally with this: https://github.com/projectatomic/buildah

@mhrivnak following on @mhrivnak's suggestion, we should target a blog post/demo in future for exploring buildah and developer workflows.
