Fixes #7

I thought that opening this PR would trigger the new workflow, but it has not. I believe this is because I am not an admin in this repo; I'm not sure if there's a way for an admin to easily approve it. This PR's status does not indicate to me that any workflows are requiring approval, as I would expect from GitHub Actions' docs.

Fom my experience running this locally, I expect a few test failures, e.g. because the IBMQ account is not configured. So I'll have to figure out how to handle these expected "failures." (EDIT: Done.)

As an alternative to calling treon directly, I could introduce a tox.ini, and then people could easily use tox to do the treon tests locally as well. (EDIT: Done.) This might be preferred, but I decided to keep this first draft simple.

Hi, While running the code, I get the solution : [[0, 1, 4], [2, 3]]

However, when I draw it using maxcut.draw(result, pos=pos):

nodes 0,1,3 are red, while 2, 4 are blue.

I have attached my jupyuter file for reference please. Kindly guide my-max-cut-qiskit-optimization-demo.pdf .

I believe this repository would benefit from having a test suite that evaluates each notebook using treon to check for any errors. Running this periodically would allow us to ensure that the code provided in these demos continues to work in future versions of Qiskit.

VQEProgram has been deprecated and VQEClient should be used instead.

In [27] the code:

runtime_result = runtime_vqe_solver.solve(problem_reduced)

returns consistently:
