After a `dokku run` container is created and started, this plugin trigger will allow developers to run auxiliary commands in response to that container.
This PR uses the new syntax for commands introduced in Docker 1.13, making it a bit easier to understand just what a particular command is trying to do.
This also pushes the long-form syntax for docker command flags, which are also easier to understand at a glance.
This will allow background processes to cleanup these files if they were unable to be cleaned up during a run of the dokku binary, as is the case for files copied by the docker binary when running in docker.
This will allow those triggers to insert and extract files from the sourcecode work directory. Note that changes are not committed to this directory, nor will they be reflected in the committed codebase.

### Tests

This is a "one-shot" ability, meaning that it is highly discouraged for multiple plugins to implement the triggers.
The `builder-create-dokku-image` trigger is meant to modify the base DOKKU_IMAGE that will be used to build an application. A good use of the hook is to inject system packages by:
- calculating an image tag from the set of system packages
- checking that the image doesnt already exist
- creating the image if it does not
As the output is sent to stdout, we have to find an alternative way of fetching the new DOKKU_IMAGE. The `builder-dokku-image` trigger can output an image tag based on the calculated image tag. If no tag is output, then the DOKKU_IMAGE is used as is.
Using this pattern, users can efficiently modify the base image in use for an app without duplicating the work on every push. This is especially useful for package installation, where packages are required for app building, but may take a long time and can be error prone.
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.
This reduces duplication and allows users to rely on global arguments to generate most labels needed.
The 'commit' command cannot have global arguments because the whitespace within the label change breaks string-based interpolation, and shell arrays cannot be exported.
The plugin creation docs were hard to follow, unnecessarily complicating issues for developers. The new format should make the recommendations clear, and align examples with the core code.

A DOKKU_SCALE file will always be used for managing the scale count for an app if it exists in a repository. As such, ps:scale usage should be disabled in those cases. This commit makes that more apparent.
Also document how to build a specific core plugin for testing purposes.
