title: How to pass arguments to get_data script in AutoMLConfig
body: <p>I am trying to run AutoML experiment on my Azure Batch AI cluster. I created the following AutoMLConfig</p>
  
  <pre><code>AutoMLConfig(task='classification',
                           debug_log='automl_errors.log',
                           path=project_folder,
                           compute_target=compute_target,
                           data_script=project_folder + "/get_data.py",
                           exit_score=0.9985,
                           **automl_settings)
  </code></pre>
  
  <p>In the get_data python script, I would like to read the data from the default datastore. Is there a possibility to pass the mounted datastore to this script as a parameter(similar to Estimator and script_params):</p>
  
  <pre><code>est = Estimator(
        source_directory=script_folder,
        script_params=script_params,
        compute_target=compute_target,
        entry_script='train.py',
        conda_packages=['scikit-learn']
  </code></pre>
  
  <p>)</p>
  
  <p>If not, could anyone please advise what is the best way to read the data from the default datastore in the get_data script?</p>
