Description of problem:
  Customer is trying to use custom certificate authority chain file. Despite of all the changes made in 
certificate files, the path to SSL chain file in apache configuration file 05-foreman-ssl.conf is wrong.
Instead of pointing to the katello-default-ca.crt it should pointing to katello-server-ca.crt where
the custom chain file is saved.


Version-Release number of selected component (if applicable):
6.1.6 

How reproducible:
Install the satellite and apply custom certificates.

Steps to Reproduce:
1. Install satellite 
2. Run katello-installer to modify the certificates
  katello-installer --certs-server-cert "/root/$SAT.crt" \
  --certs-server-cert-req "/root/$SAT.csr" \
  --certs-server-key "/root/$SAT.key" \
  --certs-server-ca-cert '/root/new_ca.crt' \
  --certs-update-server \
  --certs-update-server-ca
3. Check path to the SSL certificate chain file in the '/etc/httpd/conf.d/05-foreman-ssl.conf' file.

Actual results:
The 'SSLCertificateChainFile' option in the '/etc/httpd/conf.d/05-foreman-ssl.conf' files points 
to 'katello-default-ca.crt' instead of 'katello-server-ca.crt'

$ grep SSLCertificateChainFile /etc/httpd/conf.d/05-foreman-ssl.conf -A 1 -B 1
  SSLCertificateKeyFile   "/etc/pki/katello/private/katello-apache.key"
  SSLCertificateChainFile "/etc/pki/katello/certs/katello-default-ca.crt"
  SSLCACertificatePath    "/etc/pki/tls/certs"

Source of this error can be found in the katello-installer answer file:

$ grep server_ssl_chain /etc/katello-installer/answers.katello-installer.yaml -A 1 -B 1
    server_ssl_ca: /etc/pki/katello/certs/katello-default-ca.crt
    server_ssl_chain: /etc/pki/katello/certs/katello-default-ca.crt
    server_ssl_cert: /etc/pki/katello/certs/katello-apache.crt


Expected results:

Modification of the '/etc/katello-installer/answers.katello-installer.yaml' file will lead to correct 
path to the SSL certificate chain file in the '/etc/httpd/conf.d/05-foreman-ssl.conf'

$ grep server_ssl_chain /etc/katello-installer/answers.katello-installer.yaml -A 1 -B 1
    server_ssl_ca: /etc/pki/katello/certs/katello-default-ca.crt
    server_ssl_chain: /etc/pki/katello/certs/katello-server-ca.crt
    server_ssl_cert: /etc/pki/katello/certs/katello-apache.crt

$ grep SSLCertificateChainFile /etc/httpd/conf.d/05-foreman-ssl.conf -A 1 -B 1
  SSLCertificateKeyFile   "/etc/pki/katello/private/katello-apache.key"
  SSLCertificateChainFile "/etc/pki/katello/certs/katello-server-ca.crt"
  SSLCACertificatePath    "/etc/pki/tls/certs"



Additional info: (workaround)

Modify the answer file:
sed -i -e 's/server_ssl_chain: \/etc\/pki\/katello\/certs\/katello-default-ca.crt/server_ssl_chain: \/etc\/pki\/katello\/certs\/katello-server-ca.crt/' /etc/katello-installer/answers.katello-installer.yaml

re-run katello-installer without parameters.
