The build now happens in a loop and the monitor is run after every build. The monitor can return `ErrReload` to signal to the main thread that it should reload the build result. This will be used in the future to move the monitor into a callback rather than as a separate existence. It allows the monitor to not control the build itself which now makes it possible to completely remove the controller. Signed-off-by: Jonathan A. Sternberg <jonathan.sternberg@docker.com>
