Cannot boot Nova as quantum throws 404 when Floating IP extension unavailable

[Neela Shah]

Running with grizzly-stable.

Unable to boot nova when the quantum plug in does not support the Floating IP Extension.

The issue is with the 'self._get_floating_ips_by_fixed_and_port'. If the extension in quantum that supports that is not available, then this whole method throws an error (the 404 error thrown by Quantum).

The exception looks like the following.

This fix needs to be in grizzly as well - it is still a problem there. Will this be backported to grizzly?

    Fix more inconsistency between Nova-Net and Neutron

    The commit c62f698ef1f1e69bd5eb3c6544ee305f96488d42 fixed one
    incosistency between Nova-Net and Neutron, when Neutron returns 404
    error for list_floatingip and Nova translates it into 500 computeFault.
    However, there are two other places where list_floatingips is called.

    Move common code into private helper function, where 404 Error from
    Neutron is gracefully handled, and use it where appropriate.
