Added HOT Template for 2 Servers Without Floating IPs

Previously, a HOT template existed for deploying 2 servers using
an existing Neutron network and assigning Floating IPs to provide
public access.  This template does not work well when using
Neutron Provider Networking Extensions where Floating IPs are
unneeded to directly access instances. The template also creates
and associates the 2 servers to a Neutron Security Group that
allows SSH and ICMP.
