ufw won't work on Alpine Linux

[skyfaller]

If we can't make ufw work, maybe we should try awall instead?

This seems to be the most useful tutorial (for our purposes) we found over the course of researching awall: https://www.linuxhowto.net/how-to-set-up-a-firewall-with-awall-on-alpine-linux/

In order to configure awall, it seems we are going to need to create a handful of "policy" objects which are just json files with a single formatted json object in it in the folder /etc/awall/optional/ which we can easily make with ansible's templating once we have configured the policies that we want for our dev server. From there, the ansible module will let us enable and disable the policies that we do not want, but we will probably only put policies on there that we want anyways, but it's good to know we can toggle them on and off
