Currently, versions in README.md need to be manually updated, and we
check it's done with a bash script.
Add a small utility playbook to add versions in README.md from their
actual default values, automatically.
This is done in pre-commit, and replace the scripted check ; instead it
will autofix the README.md, and fails in CI if needed.
We switch markdownlint behind the local hooks to gave it the opportunity
to catch a problem with the rendering.
Dropping the ansible dependencies for ansible-lint will allow us to
catch missing dependencies collections in galaxy.yml. For collections
needed for contrib/ or tests/ (i.e: not part of core kubespray
dependencies), we can just configure ansible-lint to mock them.
This mean it won't check the mocked module parameters, but for those
area of the code base it's an acceptable trade-off.
Use a style file as recommended by upstream. This makes for only one
source of truth.
Conserve previous upstream default for MD007 (upstream default changed
here https://github.com/markdownlint/markdownlint/pull/373)
Allow to fail early (pre-commit time) for jinja error, rather than
waiting until executing the playbook and the invalid template.
I could not find a simple jinja pre-commit hook in the wild.
