Alex Willmer c1296b5d75 ansible_mitogen: Support ANSIBLE_SSH_VERBOSITY with Ansible >= 12
In vanilla Ansible >= 12 (ansible-core 2.19)
- ssh connection plugin `verbosity` controls `ssh [-v[v[v]]]`
- config option `DEFAULT_VERBOSITY` controls whether that output is displayed

In vanilla Ansible <= 11 (ansible-core <= 2.18)
- `DEFAULT_VERBOSITY` controls both `ssh` verbosity & display verbositty

As of this change
- Mitogen + Ansible >= 12 behaviour matches vanilla Ansible >= 12.
- Mitogen + Ansible <= 11 behaviour remains unchanged
  - `DEFAULT_VERBOSITY` only controls display verbosity.
- Mitogen + Ansible respect the Ansible variable `mitogen_ssh_debug_level`

I've chosen not to retroactively replicate the old vanilla Ansible behaviour
in Mitogen + Ansible <= 11 cases. I'm pretty sure it was an oversight,
rather than a design choice, but Ansible+Mitogen with `ANSIBLE_VERBOSITY=3`
is already very verbose.

fixes #1282

README.md

tests/ansible Directory

This is an an organically growing collection of integration and regression tests used for development and end-user bug reports.

It will be tidied up over time, meanwhile, the playbooks here are a useful demonstrator for what does and doesn't work.

Preparation

See ../image_prep/README.md.

run_ansible_playbook.py

This is necessary to set some environment variables used by future tests, as there appears to be no better way to inject them into the top-level process environment before the Mitogen connection process forks.

Running Everything

ANSIBLE_STRATEGY=mitogen_linear ./run_ansible_playbook.py all.yml

hosts/ and common-hosts

To support running the tests against a dev machine that has the requisite user accounts, the the default inventory is a directory containing a 'localhost' file that defines 'localhost' to be named 'target' in Ansible inventory, and a symlink to 'common-hosts', which defines additional targets that all derive from 'target'.

This allows ansible_tests.sh to reuse the common-hosts definitions while replacing localhost as the test target by creating a new directory that similarly symlinks in common-hosts.

There may be a better solution for this, but it works fine for now.
