Jose Diaz-Gonzalez 0a8d5eb744 refactor: add initial support for builder plugins
A builder plugin implements some method for 'building' artifacts from a given source code archive. This refactor moves the majority of the image building code into separate plugins, allowing us to implement other builders, but also simplifying the common pugin codebase.

Also move the pre-build-buildpack hook from the build-env plugin to builder-herokuish.
