- remove Python 3.10 classifier
- update requires-python to 3.11
- run mypy in python 3.11
- replace tox functional-py310 testenv with py314
- run functional-py311 instead of functional-py310 in the gate
- add a non-voting functional-py314 job (a non-voting py314 unit test
  job is already included in the openstack-python3-jobs template)
