static list_supported_drivers(output_version=1)

Returns dictionary with driver classes names as keys.

The output of the method changes from version to version, so we can pass the output_version parameter to specify which version we are expecting.

Version 1: Original output intended for human consumption, where all

dictionary values are strings.

Version 2: Improved version intended for automated consumption.

• type is now a dictionary with detailed information

• Values retain their types, so we’ll no longer get ‘None’

  or ‘False’.
