Add ABRT plugins and a dependency

rubygem-foreman_abrt
rubygem-smart_proxy_abrt
rubygem-satyr

NOTE: I used `smart_proxy_pulp` as a template, which is added under `foreman-plugins-nightly-rhel6` in `tito.props`. If I understand correctly the rhel6 plugins are built in `ruby193` collection, however the proxy itself is built without the collection - won't it lead to problems?

On the other hand, I hate copying example files from /usr/share/doc.
Let's deploy a sane config (all commented).
