We've never had the ability to build multiple images per a compose, this
commit thus rips out support for this on the API level:
image_requests is now image_request and it accepts only one ImageRequest
object instead of an array of them.

Because there's only a few combinations of upload types and image types
that make sense, enforce correct combinations by eliminating upload
types.
Fixes#1775
V2 is compliant with api.openshift.com design guidelines.
Errors are predefined, have codes, and are queryable.
All requests have an operationId set: a unique identifier which is
sortable by time. This is added to the response in case of an error.
All returned objects have the href, id, and kind field set.
