Add Ansible roles for OpenStack network

This patch also adds Vagrant provisioners for creating and destroying
OpenStack infrastructure. These are set to never run (unless explicitly
called by the operator) because DevStack instance on a separate machine
might not be ready to provide OpenStack API.

This patch is based on previous work by:
Krzysztof Opasiak <k.opasiak@samsung.com>

Test harness is based on blog post [1] by:
Chris Morgan <me@chrismorgan.info>
