Anonymous survey answers

In our organization we've come with the necessity to allow everyone to answer certain surveys, whether is registered and logged in the platform or not. We find this specially important to avoid the use of external tools where to place that data (like google forms). Of course this is a feature that has to be used with care, as it's prone to receive spam or manipulation. However, well used, can be useful to lower the barrier for certain users to participate in processes. Or just to collect specific data (emails for example). As said, we need this feature and we already implemented it (pull request pending) here: https://github.com/decidim/decidim/pull/4996 The implementation adds a new setting option in the steps process admin that allows the administrator to enable open responses to everyone.
