Subject: Allow using a provider network (#701)

* Allow using a provider network

This adds a new option `openstack_provider_network_name` which will take
a name of an existing network and put the servers there. It will also
prevent creating floating IP addresses as the provider network's IPs
should already be accessible without any additional routing required.

Fixes #622

* Requested changes

Don't fail on external/private networks and use role defaults for the
provider network.

* Add missing endif
