RFS: ruby-varia-model

Hi team!

Please upload new version of ruby-varia-model. It may break
ruby-ridley and some other berkshelf related packages, but I'm
preparing their updates.

Thanks in advance.

RFS: berkshelf for bpo9

[Hleb Valoshka]

Hi team!

Please upload berkshelf 4.3.5-2~bpo9+1 to backports. It was not fixed
in time during the freeze so I was advised to provide it though
backports.

Branch stretch-backport in git repo.

Thanks in advance.
