[Architecture] Data loaders for loading data into CouchDB

Happy to work this into our ongoing conversations around PouchDB and the
gpii-pouchdb package. Right now we use methods unique to PouchDB to load
data, but we could certainly use a similar or even the same data loader
there, at least for the grades that use express-pouchdb. The browser side
would need a little more work, but hopefully with a general enough concept
for the data loader, we would still end up with one central concept, well
exercised in a few packages.
