Create mirror of select files in Google Drive

[jeanpaulrsoucy]

We currently provide a mirror of the legacy-formatted versions of the case and death datasets on Google Drive:

• Cases HR, legacy format
• Deaths HR, legacy format

The Google Drive mirror is deprecated and should be retired/replaced with API calls as soon as possible.

This is a deprecated feature and is only supported for one specific legacy application.
