Fixes k8s neutron pod image source and formatting

Previously, the k8s neutron pod was pulling the image from
danehans instead of kollaglue. Additionally, the formatting was
incorrect causing kube not to pull the image at all.

Use hostPort to lock 1 nova-compute/nova-network per node

Kubernetes does not have a horizontal scaling feature that works per
node.  A workaround is to use hostPort to cause the scheduler not to schedule
several replicationController replicas to each node.  By doing so, only one
nova-compute is launched per node up to a total of 6 nodes which is the most
we can generate in testing.
