docs: run is a general interface that is meant for stand alone scripts to use
      when executing insights components.
  
      Args:
          root (str): None will causes a host collection in which command and
              file specs are run. A directory or archive path will cause
              collection from the directory or archive, and only file type specs
              or those that depend on `insights.core.context.HostArchiveContext`
              will execute.
          component (function or class): The component to execute. Will only execute
              the component and its dependency graph. If None, all components with
              met dependencies will execute.
  
      Returns:
          broker: object containing the result of the evaluation.
