[Vish Ishaya]

Describe addresses using the ec2 api is broken when using neutron. It attempts to retrieve the fixed ip directly which by id:

which is not supported by neutron:

It should be pulling the instance uuid from the floating list directly like we do in the v2 api:

    It attempts to retrieve the fixed ip directly,
    but it's not supported by neutron.

    After the modification,
    the instance uuid will be pulled without using get_fixed_ip().
