title: Log metrics in PythonScriptStep
body: <p>In my Azure ML pipeline I've got a PythonScriptStep that is crunching some data. I need to access the Azure ML Logger to track metrics in the step, so I'm trying to import get_azureml_logger but that's bombing out. I'm not sure what dependency I need to install via pip. </p>
  
  <p><code>from azureml.logging import get_azureml_logger</code></p>
  
  <p><code>ModuleNotFoundError: No module named 'azureml.logging'</code></p>
  
  <p>I came across a similar <a href="https://stackoverflow.com/questions/49438358/azureml-logging-module-not-found">post</a> but it deals with Azure Notebooks. Anyway, I tried adding that blob to my pip dependency, but it's failing with an Auth error.   </p>

  <p>I'm not sure how to move on this, all I need to do is to log metrics in the step.  </p>
