Comment 5 for bug 2058512

You can enabled them all like this:

    rabbitmqctl enable_feature_flag all

https://www.rabbitmq.com/docs/upgrade#enable-required-feature-flags-before-attempting-the-upgrade

But of course the ansible module doesn't seem to support that.

Edit: Tried to add support here: https://github.com/ansible-collections/community.rabbitmq/pull/170
