Description of problem:

When opening NoVNC console I see error in web UI "WebSock error: [object Event]"

Firefox browser console shows:
This site makes use of a SHA-1 Certificate; it's recommended you use certificates with signature algorithms that use hash functions stronger than SHA-1

Then I noticed certificates are still sha1

[root@rhel7-1-sat6 ~]# openssl x509 -in /etc/pki/katello/certs/katello-apache.crt -noout -text
Certificate:
    Data:
        Version: 3 (0x2)
        Serial Number: 10857288126450870211 (0x96acd606d12ba7c3)
    Signature Algorithm: sha1WithRSAEncryption



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


[root@rhel7-1-sat6 ~]# rpm -q katello-installer
katello-installer-2.3.25-1.el7sat.noarch

[root@rhel7-1-sat6 ~]# rpm -q foreman
foreman-1.7.2.53-1.el7sat.noarch

How reproducible:
All the time

Steps to Reproduce:
1.  I have been following[1] Foreman Docs, LibVirt Notes.
 http://theforeman.org/manuals/1.9/index.html#5.2.5LibvirtNotes
to configure Sat6 to connect to libvirt

2. Create https://rhel7-1-sat6.example.com/compute_resources

3. https://rhel7-1-sat6.example.com/compute_resources/1-my-test-compute/vms/cc346ba9-e054

4. Try to open console

Actual results:
