Yea I think since the existing pollster doesnt return any data, it
shouldn't be disruptive to replace with neutron api based fip pollster as i
indicated.
We can always add endpoint discovery at a later time when nova api gives
the expected fip data, so we can poll nova/neutron api's when available.
For now, I feel we should go ahead with the proposed implementation[1].

Any objections?
