Description of problem:
Say you want to make a filter based on a third party repository.
Stuff has been installed in a testsetup from that specific repository, so the rest can and should be filtered out in the content view. 

Say you cannot log into the client system, but have all power of Satellite to my disposal. One can now which packages are installed, but it's not possible to see where they came from. Running yum list installed on the host shows this, so information is available there. The information could be reported back to Satellite and shown in the ui/hammer/api 

Version-Release number of selected component (if applicable):


How reproducible:
in UI, go to content hosts/host/packages
