Add mediaserver, rm .gitignore, FQCN, Jellyfin

- Added development "mediaserver" playbook for testing
- rm .gitignore in roles dir since no external ansible roles are used
- Update a part of the base role to use FQCN for linting
- Added "jellyfin" role to install Jellyfin with docker-compose
- Updated Traefik to use the loopback for default web entry points
- Simplified Traefik docker-compose vars, Ansible sets defaults
