Review Comment:
This serialization is required when the broker inlines the subquery results
and sends the inlined query to the historicals. In that case, we serialize the
Frames and FrameBasedInlineDatasource to behave as if an equivalent
InlineDatasource (based on rows) would have been serialized.
