Add Client Cache configuration node to Client Settings object
As of right now, Client Settings are configurable during the installation of the client via command-line or via the client-side interface. I believe it would be beneficial to allow this setting to be configured via Client Settings as one organization could have a variety of different use-cases for creating disparate client cache baselines.

This is done. It seems like a dupe of this request
This is now available in SCCM 1606.
