[FR]Delete child runs together with partent runs

[PhilipMay]

When I have nested runs and delete the parent run the child runs are not deleted. Instead they are changed to top level runs.

IMO this should be changed so that child runs are deleted together with the parents.

Hey dear project maintainers @harupy and @smurching : What about this suggestion / improvement. For me my colleagues and others this might be an important improvement of MLflow. What do you think about that? Are you planning to consider this or do you just wait for an contribution?

Hi @dmatrix - maybe you could provide some feedback about this FR?

[PhilipMay]

Hello? Any news about this?

I think this is a good proposal. We can add a param delete_child_runs, to keep backwards compatibilty, set the param to be false by default. @PhilipMay Are you interested in contributing this feature ? :)
