Having both complicates the QAPI schema language and the QAPI generator. We haven't been using simple unions in new code for a long time, because they are less flexible and somewhat awkward on the wire. To prepare for their removal, convert simple union KeyValue to an equivalent flat one. Adds some boilerplate to the schema, which is a bit ugly, but a lot easier to maintain than the simple union feature.
