Subject: [PATCH] Remove usage of deprecated Flask variable
 `_request_ctx_stack`, use `request`; refactor span callback tests to address
 change in Flask where before/after request callbacks can't be added to an app
 once it has started serving requests; add `flaky` decorator to
 `test_request_distinct` and `test_over_wire` unit tests; add Python 3.10
 compatibility hack to example server and client scripts; change testing to
 use `tox` instead of deprecated `python setup.py test`; add recent Python
 versions to tox.ini envlist
