Description

(Previous title was "Refactor DatasetRef into multiple better-defined classes", but now we're changing DatasetRef).

The current DatasetRef has too many fields (provenance stuff we never use), too many states (whether or not it has a dataset_id completely changes what it represents), and ill-defined comparisons. It's almost-but-not-quite immutable, which makes it tempting but a bit dangerous to use as the key type in a set or dict.
