Allow to sample Lists of Hyperparameters

[Alken0]

As a automl-developer I want to to create a network with n layers of different with.
Currently I cannot sample the with easily, I have to create an extra entry for each layer.
To make my life easier I would like to sample a list of Hyperparameters like so:

"layer_width": List(Integer("layer_width", (10, 100)), length=100)

It would be even better if the length could be dynamically adjusted, depending on another Hyperparameter.
