Jim Rollenhagen e55cf73890 Ironic: enable multitenant networking
This replaces the unused code (due to API versioning) in the ironic
driver's implementation of `network_binding_host_id`, to code that
actually enables the multitenant networking support in ironic.

While building this out, we changed direction and ended with the node's
field being called `network_interface` instead of `network_provider`.
This patch changes this to match, and bumps the ironic API version used
to 1.20, where this feature is introduced.

The old code also assumed ironic would have only two network interfaces,
"neutron" and "none". This became three - "neutron", "flat", and
"noop".[0] "neutron" is the only interface that requires returning None
from `network_binding_host_id`, while the others should match the old
behavior. Change the code to only do this for the neutron network
interface, instead of doing this for anything not called 'flat'.

features:
- Multitenant networking for the ironic compute driver is now supported.
To enable this feature, ironic nodes must be using the 'neutron'
network_interface.
upgrade:
- The ironic driver now requires python-ironicclient>=1.5.0 (previously
>=1.1.0), and requires the ironic service to support API version 1.20 or
higher. As usual, ironic should be upgraded before nova for a
smooth upgrade process.
