Make sure that all created networks built for neutron are working. This script assumes that you have already created your neutron networks and that you have built the appropriate subnet for the network. This script also assumes that you have at least 1 image to build with.

# Test an attach neutron network and ping the Gateway
# This script will build 1 instance per network then it will ping the 
# Network gateway from within the network namespace.

# Variables:
#   FLAVOR=The flavor size ID, defaults to 2.
#   IMAGE=Image ID, defaults to the first found image ID.
#   KEYNAME=Name of a keypair, defaults to "PrivateCloudTest".
