Over quota errors originating from Neutron result in 500 error in Nova

[Phil Day]

When using the floating IP and SecGroup extensions in Nova with Neutron, and a quota limit is exceeded in Neutron, the exception from the Neutron client results in Nova generating a 500 error.

This is unhelpful to to user, and not consistent with nova-networking

    Handle IpAddressGenerationClient neutron

    Handles IpAddressGenerationClient neutron exception which
    can occur when allocating a floating ip fails because
    the pool has been exhausted. Convert the exception
    to a nova NoMoreFloatingIps exception which will be handled
    by the api layer and converted to a 404.
