Review Comment:
I've tried quickly adding this field to serialisation, but it does not look
trivial to me, I'm not so sure anymore that it's worth doing and I can't spend
to much time on this right now unfortunately. If it can't be merged in current
form let's close the PR for now - maybe I'll revisit in the future 😄 For now
I'll advice the OL consumers to use AirflowDagFacet that has the taskTree with
all the task dependencies in the DAG. Thanks for the comments and engagement !
