Can we have example of utilizing one-shot NAS for DNN models?

[ZhuJohnson]

What would you like to be added:
More example for one-shot NAS practice of DNN/MLP models
Why is this needed:
Didn't find this kind of example in the repo.
Without this feature, how does current nni work：

Components that may involve changes:

Brief description of your proposal if any:
I'd like to apply NAS function to search the model structure for MLP(to searchhow many hidden layer/how many neurons in each layer/activation function/dropout rate/ layer type(dense or denseblock)), but I cannot find any examples about this problem in the repo.

Good suggestion. Some of what you want can be naturally fit into current one-shot algorithms (e.g., activation function), while for others we need to find papers and even improvise as current one-shot NAS might not work at all.

In summary, we have to investigate what is going on. For now, let's put it into our future plan.
