Check for network information in config #482

If I try to start a cluster without network information, elasticluster should complain before even trying to build the cluster. As it is, it will try and then gives a rather obscure error message:

The error really comes from OpenStack and bubbles through layers until it hits ElastiCluster.

What's not clear to me is whether it is now always required in OpenStack to specify a network in order to start a VM, or if it's an installation option (i.e., depends on the OpenStack sysadmins -- some may still configure with a default network for all VMs).

In the first case, I agree that network_ids should be made mandatory.
