Python 3.x emits `ResourceWarning`s if certains resources aren't correctly
closed. Due to the way Mitogen has been terminating child processes this has
been occurring.
```
test_dev_tty_open_succeeds
(create_child_test.TtyCreateChildTest.test_dev_tty_open_succeeds) ...
/opt/hostedtoolcache/Python/3.12.5/x64/lib/python3.12/subprocess.py:1127:
ResourceWarning: subprocess 3313 is still running
_warn("subprocess %s is still running" % self.pid,
ResourceWarning: Enable tracemalloc to get the object allocation traceback
ok
```
During garbage collection subprocess.Popen() objects emit
ResourceWarning("subprocess 123 is still running")
if proc.returncode hasn't been set. Typically calling proc.wait() does so,
once the sub-process has exited. Calling os.waitpid(proc.pid, 0) also waits
for the sub-process to exit, but it doesn't update proc.returncode, so the
ResourceWarning is still emitted.
This change exposes `subprocess.Popen` methods on
`mitogen.parent.PopenProcess`, so that the returncode can be set.

This
- Removes the indirection of calling ansible in a sub-shell
- Includes vanilla Ansible, which was previously skipped
- Tests whether ansible_ssh_pass overrides ansible_password, as it should
As a one off I've the new tests against vanilla Ansible 2.10 through Ansible
10, to confirm the baseline priorities have remained unchanged all releases
currently supported by Mitogen 0.3.x.
The bug was fixed in a previous commit by Jonathan Rosser. This adds testing.
The bug is only triggered when the copy module is used inside a `with_items:`
loop and the destination filename has an extension. A `loop:` loop is not
sufficient.
refs #1110
This is in anticipation of #1110, which only exhibits inside a with_items:
loop. For this refactor `loop:` is used, to confirm the refactored tests are
still correct. A subsequent commit will change them to with_items.
The content of the files and their SHA1 checksums are unchanged.
Relying on the virtualenv default or hardcoding "python" results in a Python
2.x virtualenv on some targets (e.g. debian10-test). This caused a failure
when testing with Ansible >= 10 (ansible-core >= 2.17), which have dropped
Python 2.x support.
refs #1074
By setting ansible_python_interpreter for these fictious hosts we avoid
Ansible trying and failing to connect to them in a attempt to populate
ansible_facts.discovered_interpreter_python. This speeds up these tests by
avoiding a timeout.
It is also a necessary pre-requisite for Ansible 10 (ansible-core 2.17). In
that release no hardcoded fallback is used, failure to determine a valid
Python interpreter is a fatal error.

Pip 72 was released yesterday (2024-07-28), dropping `setup.py test` support.
hdrhistogram 0.6.1 requires it to install.
For now constrain Pip to earlier releases, so our tests can be run.
refs #1090
macOS 11 is not longer an available runner on Azure Devops. The minimum is now
macOS 12. This runner does not have Python 2.7 installed, so running them
would require a custom install - which I'm declaring too much effort for too
little gain.

CentOS 8 has reached EOL. Packages are no longer mirrored or maintained. A
historic snapshot of the packages is kept on vault.centos.org.

Follwing fixes in Ansible 7-9 for CVE-2023-5764 cating `AnsibleUnsafeBytes` &
`AnsibleUnsafeText` to `bytes()` or `str()` requires special handling. The
handling is Ansible specific, so it shouldn't go in the mitogen package but
rather the ansible_mitogen package.
`ansible_mitogen.utils.unsafe.cast()` is most like `mitogen.utils.cast()`.
During development it began as `ansible_mitogen.utils.unsafe.unwrap_var()`,
closer to an inverse of `ansible.utils.unsafe_procy.wrap_var()`. Future
enhancements may move in this direction.

If casting a string fails then raise a TypeError. This is potentially an API
breaking change; chosen as the lesser evil vs. allowing silent errors.
`cast()` relies on `bytes(obj)` & `str(obj)` returning the respective
supertype. That's no longer the case for `AnsibleUnsafeBytes` &
`AnsibleUnsafeText`; since fixes/mitigations for CVE-2023-5764.

Most of the necessary changes were made in recent PEP 451 commits. This bumps
the CI jobs, and declares the support. Test dependendancies are bumped to
latest supportted/available versions.
refs #1033
importlib.machinery.ModuleSpec and find_spec() were introduced in Python 3.4
under PEP 451. They replace the find_module() API of PEP 302, which was
deprecated from Python 3.4. They were removed in Python 3.12 along with the
imp module.
This change adds support for the PEP 451 APIs. Mitogen should no longer import
imp on Python versions that support ModuleSpec. Tests have been added to cover
the new APIs.
CI jobs have been added to cover Python 3.x on macOS.

Using https:// requires certificate store management and additional parameter
passing that changed across Ansible and Python versions. Using http:// allows
the same tests to be used across wider spans of Python version on the
controller, and Python verison on the targets.
Python 3.12 on a target + get_uri needs Ansible >= 8 (ansible-core >= 2.15).
Python 3.12 removed deprecated httplib.HTTPSConnection() arguments.

To do so the test suite allows a weak cryptographic alogorithm (SHA1) to be
used, principally for CentOS 6 targets. This can be removed if/when support
for older (legacy) targets is dropped.
Only the test suite enables this known weak alogorithm. Mitogen as-shipped
doesn't enable or disable algorithms.
