This commit updates all files that weren't passing yamllint for them to
pass.
A new yamllint target has been added. One can run `tox -e yamllint` or
`yamllint -s .` locally to ensure yaml files are still passing.
This check will be enabled in the CI so it can get on every new
contributions, and prevent merging non-compliant code.

Prior to this change, password having shell interpretable character
would break the installer (e.g '&', '(', etc... )
This commits rely on the `quote` filter from ansible to ensure those
password are properly quoted where it applies
