Ma/fetch org authz

Creating a PR for this so I can comment and fix
Combining this with the branch of `chef_wm` and the changes to `chef_wm_base`, we're actually now removing the cache of orgname -> guid when making requests to couchdb. By deploying this set of changes, we'll effectively remove that cache. That should stay until we're full off of couchdb. I'll push changes in a sec that address this.
