images rendering at native size on page

[PaulReiber]

Formatting cleanup.

The page displays two images:
http://docs.openstack.org/security-guide/_images/sdn-connections.png
http://docs.openstack.org/security-guide/_images/1aa-network-domains-diagram.png

One is reasonably sized, the other is much larger. Both could be better positioned and sized.
