This is no longer being used due to Keystone PKI tokens no longer being implemented. In order to not break backward compatibility we create a new function that is to be used instead and deprecate the old one. Modify the old function to ignore the 3rd argument and display a deprecation warning. Adjust callers to no longer create and set that directory, calling the new function instead.
