Type 2: Update Data Source Field Description

[jamesrudolph]

Summary

It would be very helpful to be able to edit a Data Source Field Description via REST api (and subsequently scp).

Description

With the Metadata API, it is possible to update a Table's Column Description which does get inherited into the Data Source Field Description, however, it would be very helpful to be able to edit the Data Source Field Description directly.

We are trying to fully leverage the Data Management addon and automate the copy of our data dictionaries to Tableau descriptions, but only being able to add these to add the Table Column level is limiting. We can't add descriptions for Calculated Fields, for example.
