Attach assets to the draft instead of to every lifecycle row

Node#attach_asset! writes to the node's draft alone, creating one from the
head when none is pending. It refuses when another user holds the lock, and
when an autosave already exists

The asset_attach verb goes with it. create_new_draft names the editor on the
draft it creates and the publish entry's asset delta reports the attachment.
