feat(namespace) : Simplify driver namespace

the storage and metadata directories are removed.
True it is something to think about.

However, I think the structure provides the resolution, and using common names for the modules would make it easier to setup new modules. So instead of having to copy/rename you can just copy a template and fill in the functionality (or copy an existing and modify it as required). Saves a step in those parts, and saves some typing whenever we need to pull those in.

@painterjd @raxyu - what do you guys think?
