Don't add key_url as it is deprecated and not needed when
pkgrepo_keyring is set. This has been supported since stretch so make it
the default. Also use py3 repo by default for Debian family as it is now
the only option.
Additionally, Raspbian has been updated to use signed-by by default.
Avoid this error:
```

Make the upstream salt package repository selectable, thus allowing the
use of archived salt versions (hosted in
https://archive.repo.saltproject.io), as well as custom salt versions
hosted in alternate repositories.
