Fixes #29664: Update Candlepin port to new default

[ehelms]

Does not "require" theforeman/puppet-candlepin#156 but I would like them to be in sync default wise and resolve the port number conversation.

As mentioned in theforeman/puppet-candlepin#156 (review), I think this commit should be Fixes.

I'd like to get #339 in before this

[ehelms]

From my testing, this will require SELinux changes. @lzap can you help with that when you have time? I imagine they would be in the katello-selinux policy.

Tested full install piepline with the SELinux change here -- theforeman/katello-selinux#26

[root@pipeline-katello-server-nightly-centos7 vagrant]# netstat -nlp | grep 23443
tcp6       0      0 127.0.0.1:23443         :::*                    LISTEN      26510/java          
[root@pipeline-katello-server-nightly-centos7 vagrant]# netstat -nlp | grep 8443

There's now a conflict. I also think this should be Fixes #29664

[ehelms]

The commit was already fixes but I updated the MR title to reflect the same. This is waiting on final review of theforeman/katello-selinux#29

[ehelms]

Are we OK with merging and making this change now?

[ekohl]

I'm labeling this as backwards incompatible because I think this deserves a major version bump. I don't want to risk accidentally cherry picking a minor version in a stable release.
