docs: Decorator used to mark a test as "flaky". When used in conjuction with
      the flaky nosetests plugin, will cause the decorated test to be retried
      until min_passes successes are achieved out of up to max_runs test runs.
  
      :param max_runs:
          The maximum number of times the decorated test will be run.
      :type max_runs:
          `int`
      :param min_passes:
          The minimum number of times the test must pass to be a success.
      :type min_passes:
          `int`
      :param rerun_filter:
          Filter function to decide whether a test should be rerun if it fails.
          Function signature is as follows:
              (err, name, test, plugin) -> should_rerun
          - err (`tuple` of `class`, :class:`Exception`, `traceback`):
              Information about the test failure (from sys.exc_info())
          - name (`unicode`):
              The test name
          - test (:class:`nose.case.Test` or :class:`Function`):
              The test that has raised an error
          - plugin (:class:`FlakyNosePlugin` or :class:`FlakyPytestPlugin`):
              The flaky plugin. Has a :prop:`stream` that can be written to in
              order to add to the Flaky Report.
      :type rerun_filter:
          `callable`
      :return:
          A wrapper function that includes attributes describing the flaky test.
      :rtype:
