selinux permissive on Fedora

The f20 gate job is failing on hpcloud images
(official F20 cloud image), with enforcing selinux.

Setting selinux to permissive on all Fedoras.

Currently selinux policies are violated, when
 - horizon/httpd tries to access a files without
httpd_t friendly security label.
 - horizon/httpd_t tries to connect to openstack
   service port, without an allowing policy.
 - swift tryes rsync content without an authorized
   security label and without rsync_full_access sebool.
 - ..

In permissive mode you will be able to track,
the missing policies and labels by checking
the /var/log/auidit/audit.log*

The enforcing mode might be turned on in the future,
when all label and policy configured correctly.
