Review comment:
Need a TODO here about the main output of external transforms being
ambiguous. Or, could it be the only element of
set(ransform_node.outputs.keys()) - set(side_tags)?

> 'ExternalTransform.expand()' can be used to expand a remote transform and
> build the correct runner-api subgraph for that transform. However currently
> we do not modify the AppliedPTransform sub-graph correctly during this
> process. Relevant code location here.

>
> Without this, DataflowRunner that relies in this object graph (not just the
> runner API proto) to build the job submission request to Dataflow service
> cannot construct this request properly.
