Preparation for Netbox 3.5

- Reports and Scripts have changed in Netbox 3.5. They need to be uploaded now.
  The Docker compose now creates a volume as it does for the media files
- Napalm has been removed from Netbox 3.5
  All configuration entries for Napalm were removed and napalm itself is removed from the requirements file
- Removed Gunicorn from the image
  Nginx Unit has been used for a while now. No need to install Gunicorn
