This adapts PR #740 by @extmind (afe0026890),
which augmented the call to `Connection.get_task_var()` with
`C.config.get_config_value('INTERPRETER_PYTHON'` as a default. Instead this
*replaces* the call to `Connection.get_task_var()`. The aim is greater
simplicity by disentangling templating of a configured interpreter path and
discovery of an interpreter when none is configured. I think this also reduces
the number of times `Connection._get_task_vars()` is called, so reducing the
number of times we do the ugly stack frame inspection.
I've also added test cases.

Ansible >= 4 (ansible-core >= 2.11) the SSH plugin has a `timeout` option and
with variable `ansible_ssh_timeout`, but not a `ansible_timeout` variable.
The local plugin has no such option or variable(s). However `ansible_timeout`
is backfilled for all conection plugins, by legacy mechanisms that populate
the play context attribute:
- `ansible.constants.COMMON_CONNECTION_VARS`
- `ansible.constants.MAGIC_VARIABLE_MAPPING`
The `timeout` keyword is for task completion timeout, not connection timeout.
This tightens up our monkey patching `Connection._action` so it's only applied
during `meta: reset_connection` & promptly removed. This fixes "'int' object
has no attribute 'template'" when `ansible.plugins.action.wait_for_connection`
or other code calls `ansible.plugins.connection.ConnectionBase.reset()`.
This could also have switched to `templar=templar` on the temporary action,
rather than `templar=0`, but it's not strictly necessary to fix this bug. I
anticipate other changes doing so soon, to improve interpreter discovery &
templated python interpreter path support.
The code change to support this was already made in transport_config.py, as
part of templated become_user support (commit bf6607e27e, PR #1148). This
commit adds tests to confirm the functionality.
The wrong base was used when calculating the mode. So the file became world
readable and writable on a CI runner, until
ansible/integration/ssh/variables.yml happened to correct it near the end of
the integration tests.
I believe this was the only instance.

Adding a the tt-ssh-executable test target uncovered an Ansible bug during
`meta: reset_connection` tasks. So this commit includes a workaround for
affected versions of Ansible.
Uses the same fallback for (mitogen_sudo et al) as become_exe (see #1173).
The new `Spec.become_flags()` is not yet explicitly tested. Note that it
returns a string (matching the Ansible option of the same name), whereas
`Spec.sudo_args()` returns a list.

Some ansible_mitogen connection plugins look more like become plugins (e.g.
mitogen_sudo) & use become plugin options. For now there's special handling in
PlayContextSpec._become_option(). Further design/discussion can go in #1173.
Refs #1087.
The tasks in tests/imageprep/_user_accounts.yml that create users did not
specify a primary group for those users - this left the decision to Ansible's
user module, and/or the underlying OS. In Ansible 9+ (ansible-core 2.16+ the
user module defaults to primary group "staff." Earlier don't supply a default,
which releases probably results in a primary group nameed "None" (due to
stringifying the Python singleton of the same name), or whatever the macOS
Directory Services has for no data/NULL.
The invalid GID 4294967295 (MAX_UINT32 == 2**32-1) in the sudo error probably
enters the mix via something similar to sudo CVE-2019-14287.

This reads the become username from the `become_user` attribute of the play
context, to the `"become_user"` option of the loaded become plugin. This has
been supported by vanilla Ansible since Ansible 2.10 (ansible-base 2.10).
To support this I've also switched from using the `play_context.become` (a
bool), to `connection.become` (an instance of the appropriate) become plugin.
New tests have been added, modelled on those for templated connection
parameters (see #1147, #1153, #1159).
