Apache::Params is incorrectly changing httpd config directory on CentOS-7

httpd is failing to come up and the error in /var/log/messages:

Feb 29 22:18:41 localhost httpd: AH00526: Syntax error on line 31 of /etc/httpd/conf.d/php.conf:

According to: http://serverfault.com/questions/515417/error-start-apache-php-value this is caused by a missing libphp5.so file.

At first I thought there was a missing "Load Module" line not getting inserted into the config yet after looking closer I see that logic one line 65 of https://github.com/redhat-openstack/openstack-puppet-modules/blob/master/apache/manifests/params.pp changes the module config directory for RHEL/Centos-7.

I'm not sure this is 100% correct but I watched this multiple times by removing packstack then performing a first 'failed' install where I saw both conf.d and conf.modules.d get created and populated. Once the keystone.pp failed I copied the files from /etc/httpd/conf.modules.d into /etc/httpd/conf.d and the httpd service started right up.

I then executed another packstack install on top of the system/failure and all completed as expected.

Not sure the best way to resolve comment 5 ( https://bugzilla.redhat.com/show_bug.cgi?id=1276277#c5 ) recommends an update to httpd.conf which seems feasible.
