* ansible-test - Remove cap on cryptography version.
(cherry picked from commit 00a2b7788e)
* ansible-test - Fix consistency of managed venvs. (#77028)
(cherry picked from commit 68fb3bf90e)
* Avoid system-site-packages in AZP coverage venvs.
The use of `--venv-system-site-packages` was an optimization to use the `coverage` package pre-installed in the AZP test container.
However, now that the venv is bootstrapped by ansible-test that optimization no longer makes sense, since other downloads are already taking place.
(cherry picked from commit 177336a9d3)
* ansible-test - Clean up venv code.
(cherry picked from commit addb9baec2)
* Adjust virtualenv version for Python 2.6.
* Adjust bootstrap URL to work with Python 2.6.
* Enable PyPI proxy for generic tests.
This is needed to support ansible-test integration tests on Python 2.6.
* Freeze plugin import sanity test requirements.
