Update directory structure

[sjberman]

Problem: Now that the original provisioner mode has been removed, we don't need the nested mode/static directory structure. The naming no longer makes sense.

Solution: Updated mode/static directory to controller, and moved some of the framework packages into controller. Other packages in framework were left alone since many of them are general enough for "controller building" use.
