[QUEUES] Allow jobs created on `Component` creation to be passed onto downstream components

[blythed]

1. Compute features
2. Train PCA on finished computed features
3. Compute dimension reduced features

class DimReduceModel(Model):
    trainer: ...
    upstream: ...

listener1 = Listener(features_model, ...)
dim_reduce_model = DimReduceModel(trainer=PCATrainer(), upstream=[listener1])
listener2 = Listener(dim_reduce_model, ...)

Explanation

• The listener1 creates features
• dim_reduce_model trains on those features
• listener2 creates features after the training is complete
