Some errors are invoked outside of negotiation. These errors should
still have a kind and apiVersion (which is only set by structured
encoders, not always availabe). Ensure that all errors by default get a
status kind and version set.

All generic registries expose metadata output, and refactor endpoints to
allow negotiation to handle those responses. Add support for
PartialObjectMetadata being returned for objects as well.
