* Add update_password parameter to rabbitmq_user
Inspiration for this feature is taken from the `user` module.
While `always` is the default in that module, it is not here. We default
to `on_create` to avoid changing existing behaviour.
Resolves#29260
* Update instructions for changing passwords
* Bump version_added as requested
* Check password before changing it
This allows accurate reporting of changed status even though
`rabbitmqctl change_password` doesn't.
* Remove instruction to use 'force' to update password
