/**
 * PreviewPluginFinder is an extension of {@link RemotePluginFinder} that is meant to be used exclusively in tasks
 * running in the {@link PreviewRunnerTwillRunnable}. This implementation uses the {@link ArtifactLocalizerClient} to
 * download and cache the given artifact on the local file system; however, it does not unpack the artifact as the
 * SparkCompiler may require it packed to function properly. See CDAP-19311 for details.
