Create selinux policy module for httpd webroot

[jeff1evesque]

We need to define the selinux system context for the webroot directory. Otherwise selinux will not allow httpd to render the corresponding drupal webpage(s).

Note: this means we will need to rebuild our vagrant base box, and update the corresponding atlas jeff1evesque/centos7x repository.

The following commands created our selinux policy modules, within the vagrant base box:

$ sudo yum install setroubleshoot
$ sudo setenforce permissive
# do a bunch of drupal operations, to log all the policies within the audit file, before performing the below
$ sudo grep httpd_t /var/log/audit/audit.log | audit2allow -M httpd_t

Then, we vagrant up, since enabling the selinux policy module, is incorporated within configure_httpd.pp.
