nmcli: Change hairpin default mode (#4334) (#4558)

* nmcli: Deprecate default hairpin mode Deprecate the default hairpin mode for a bridge. Plain nmcli/bridge tools defaults to no, but for some reason ansible defaults to yes. We deprecate the default value so we can switch to default 'no' in ansible 6.0.0 * Code review fixes Co-authored-by: Felix Fontein <[email protected]> * Fix comments * Update changelogs/fragments/4320-nmcli-hairpin.yml Co-authored-by: Felix Fontein <[email protected]> * Update changelogs/fragments/4320-nmcli-hairpin.yml Co-authored-by: Alexei Znamensky <[email protected]> Co-authored-by: Felix Fontein <[email protected]> Co-authored-by: Alexei Znamensky <[email protected]> (cherry picked from commit 53f6c68) Co-authored-by: dupondje <[email protected]>

+  - nmcli - deprecate default hairpin mode for a bridge. This so we can change it to ``false`` in community.general 7.0.0, as this is also the default in ``nmcli`` (https://github.com/ansible-collections/community.general/pull/4334).
