* Use default group of staff on macos to prevent sudo issues
* Install gnu-tar for macos in git and unarchive tests
* Enable timezone module to support py3 on macos
* If the virtualenv command is missing, try python -m virtualenv
* Install passlib for filter_core on macos
* Install paramiko via pip on macos for paramiko tests
* Normalize discovered python interpreter on macos
* Get pip tests passing, by ensuring we have wheel installed
* Create /etc/ansible for ca certs on mac, list lookup_url as destructive
* Fixups for CA certs
* Include macos
* Dynamically get cafile instead of hardcoding the path
* Python interpreter discovery
* No longer blindly default to only `/usr/bin/python`
* `ansible_python_interpreter` defaults to `auto_legacy`, which will discover the platform Python interpreter on some platforms (but still favor `/usr/bin/python` if present for backward compatibility). Use `auto` to always use the discovered interpreter, append `_silent` to either value to suppress warnings.
* includes new doc utility method `get_versioned_doclink` to generate a major.minor versioned doclink against docs.ansible.com (or some other config-overridden URL)
* docs revisions for python interpreter discovery
(cherry picked from commit 5b53c0012ab7212304c28fdd24cb33fd8ff755c2)
* verify output on some distros, cleanup
