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.

Fixes: bug #1168573
Change-Id: I7b1754b0e59a923afa623871fc3be07362bf1bdc
