Switch to live from noop drivers

Browse Source 
The switch to live drivers ease greenfield deployments by not requiring
deployers to explicitly set live drivers. The switch also helps
deployers identify production-ready from experimental drivers.
Experimental features like volume and distributor remain defaulted to
their noop drivers.

This patch also fixes some tests that were not mocked properly.

upgrade:

The default drivers have been switched to live from noop drivers for the
most part. Volume and distributor remain set to noop drivers as those are
experimental features. Operators do not need to make configuration changes.
