Fixes an get_volume_stats reporting issue

This patch fixes a bug introduced in the last get_volume_stats
patch that caused the method to fail.  I Also added another set
of unit tests to catch any future issues related to get_volume_stats.

Fixes Bug: #1178418

Deprecating old dot path locations for Folsom configs

In grizzly, we made a lot of structure changes. This deprecates the old
locations so the dot paths in old configs still work but give warnings
in the logs of what needs to be updated.
