Separate Media Domain for Akkoma

The last release of Akkoma finally enforces setting a base_url value for the uploader (guess who didn’t read the release notes before upgrading and had to start digging after the service refused to start).

To enable akkoma to start again I set the base_url value to the main domain of my akkoma instance but this still leaves a rather stern warning to switch to another domain for uplaods (and the media proxy if you use it).

So I created a CNAME for the upload domain and added another nginx server section that basically only serves the uris /uploador /media and forwards them to phoenix, all other requests will be forwarded to the main domain.
