Remove unnecessary ini commenting from nova

Nova does not ship these options in it's api-paste.conf any more so the
functions have no effect.

a more proper default nic selection criteria

look at all interfaces that ip link shows as being up, then filter
them for ^e or ^p devices. Should hold even after the bridges get
built.

Use apache2ctl after apache is installed.

Ensure that apache2ctl is only called if apache2 is being used when
setting up Keystone. This patch corrects a case where apache2ctl
is being called at the time lib/keystone is being sourced. This
error breaks attempts to deploy Keystone under apache unless
apache is already installed at the time stack.sh is run.

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.

Install 'ipmitool' package for Ironic

Ironic's reference / recommended driver is the "pxe_ipmitool" driver,
which requires the 'ipmitool' package and system binary. Thus,
devstack should install it.

Also, Ironic will soon be validating that ipmitool is present in the
system path when loading the pxe_ipmitool driver, as it does for other
drivers (seamicro, pyghmi) that have external dependencies.

Causing devstack to install this package when Ironic is enabled will
also help users who wish to test Ironic against physical hardware that
has IPMI support, without having to perform additional manual steps
(like enabling the pxe_ipmitool driver and installing the ipmitool
packge by hand).
