Drone: Add Python 3.10 to the testing

[cclauss]

Fixes #

Proposed Changes

• Add Python 3.10 to the testing

---

Nose is incompatible with Python 3.10 which has finally removed the alias between collections and collections.abc.

• Perhaps upgrade to https://docs.nose2.io or https://docs.pytest.org

  File "/usr/local/lib/python3.10/site-packages/nose/suite.py", line 106, in _set_tests
    if isinstance(tests, collections.Callable) and not is_suite:
AttributeError: module 'collections' has no attribute 'Callable'

https://docs.python.org/3/library/collections.abc.html#collections.abc.Callable

We are going to have to do work to get this passed. I do want to support 3.10 ASAP and I also want to move away from nose, to pytest.

We might just have to leave this unmerged until the Callable fix is merged first.

Agreed. In fact, these mods should be part of #1268
