DRY: Build ImageMetaPropsPayload from ImageMetaProps
ImageMetaPropsPayload (for notifications) was supposed to contain exactly the same fields as ImageMetaProps itself; and the SCHEMA member was those same keys in a trivially different shape. And we were having trouble remembering to keep these two objects in sync before. So this commit eliminates the repetition and just generates ImageMetaPropsPayload's `fields` and `SCHEMA` from ImageMetaProps.fields. Change-Id: I7dc38f7f5a62098fb0c366736f27e23bd7b7ee86

This has the following implications:

the version of this object, even though you didn't make any explicit

``nullable=True`` or with a ``default``), something needs to change here.
