As you mentioned, @oferrigni, this is missing a `#context{}` argument and stats_hero instrumentation (which would pick up reqid from the context).

Interesting to observe that if we didn't have the context to pass around, the chef_wm code could just as easily call chef_object:list as chef_db:list. But the instrumentation and reqid has a lot of value and I guess I also like having the places where we're doing db stuff being explicit.
