Corect filtering of OpenStack LBaaS resources to update
Corect filtering of OpenStack LBaaS resources to update

Neutron's API ignores unknown paramaters. When listing pools etc, K8
attempts to filter on "LoadBalancerID", which is not a valid filter.
As such, it is ignored by Neutron, and a list of all pools is
returned. K8 then proceeds to update each of the pools.

Instead, we now double check the resources really belong to the LB
we're trying to update.
