storage: select which attributes are returned for listing

This is added as an optimization, since a lot of the time taken for
listing large buckets is spent encoding and decoding attributes in JSON.
Clients who are only interested in listing object names don't need a lot
of the data that gets encoded and sent down the wire, so using a new
selection in Query they can speed up their listing by up to 33%
