Jupyter notebooks and visualizations should be moved to a different package

In the quest for lighting Terra, it seems to me that there is some consensus for moving notebooks [1, 2] (and the associated visualization tools [3]) to a different repo/package, since they effectively are a layer on top of Terra.

The task associated with this are:

• Confirm the consensus
• Choose a name a create the repo/package
• Move code, tests, and issues for:
  • Non-text visualizations associated with notebooks (circuit, city plots, etc)
  • Jupyter tools in qiskit/tools/jupyter

This will allow us to move towards a totally network-independent Terra, to reduce the noise associated with issues and PRs on the jupyter layer, and to light dependencies.

For what is worth, I agree with @1ucian0 and believe that moving that layer to another package is a sensible thing and hope it can be reevaluated at some point.

The move would not imply reducing the importance of visualizations, nor incur in changes to the stable interface - as a matter of fact, it would be pretty transparent and straightforward. We already have an example of that transition in the split of the IBMQProvider, which did contain similar implications (popular feature and stable interface) and was rather uneventful.

With the risk of re-hashing older discussions, I think we should also throw into the mix the importance of a lean terra not only for 1.0, but for the present work in other areas. So basically +1 to @1ucian0 !

I dont remember any user complaining about that. It’s mostly about testing time and responsibility separation.
