nose is deprecated and EoL

[Kyle Mandli]

Hi everyone,

I am not sure if anyone has noticed but as of Python 3.10 `nose` breaks.  Looking into it a bit I noticed the following discussion on the nose GitHub issues tracker:

https://github.com/nose-devs/nose/issues/1099

Seems that they are recommending to move over to `pytest` or at the very least a new version of `nose`, `nose2`.  I do not think we have much in the way of specific `nose` code so this could be an easy transition but I have not looked at it too closely.

Thoughts on this?

Nevermind, looks like it's going to be some work to transition to pytest.
