Revert "Simplify variables in katello::qpid"

[stbenjam]

Reverts #119

This broke the pipeline:

21:49 [-beav > ==> centos7-devel:  qpid-config --ssl-certificate /etc/pki/katello/certs/centos7-devel.example.com-qpid-broker.crt --ssl-key                                                                        
               /etc/pki/katello/private/centos7-devel.example.com-qpid-broker.key -b 'amqps://centos7-devel.example.com:5671' bind event  '*.*' returned 1 instead of one of [0]

For some reason $candlepin_event_queue doesn't seem to be in scope. Maybe @ekohl has an idea why, but I'd be inclined to just revert this for now and revisit the clean-up later so the pipeline gets going again.

[beav]

the pipeline itself is green, this is for devel setup but is also important 🐨

I'll do a run w/ this patch asap to see if it runs cleanly

[beav]

I get a clean run after applying this patch and re-running foreman-installer (I was already set up to use the devel scenario).

[stbenjam]

Ohhh sorry, thought I saw somethng on foreman-dev earlier. This is still likely the cause. For some reason $candlepin_event_queue isn't available when puppet-katello_devel calls ::katello::qpid.

[stbenjam]

I see, katello_devel calls ::katello::qpid, but the top-level namespace (::katello) where candlepin_event_queue is, isn't loaded.

I guess the best fix would be for katello_devel to pass the queue explicitly.

This should fix it: theforeman/puppet-katello_devel#72

Will test.

But no need to revert this change IMHO.
