[pve-devel] [RFC common 2/7] APT: add extended repositories check

To detect old/bad suites and see whether the 'enterprise' repository or at least
the 'no-subscription' repository is configured.

Suggestions for further checks are welcome.

Note that the distribution names might conflict for external non-Debian repos
that would re-use Debian names, but I think we can safely ignore that.
