CV Publish with errata filters can send incorrect packages to pulp
If you publish a CV with filters
Sync down two repositories with the same errata, such as el6 & el7 satellite tools.
Add them to a content view
create a filter to include an errata that is in both repositories
monitor the copy calls going to pup2, by logging 'rpm_copy_clauses' here: https://github.com/Katello/katello/blob/master/app/services/katello/pulp/repository/yum.rb#L111
You will see el6 packages attempting to be copied into the el7 repo
