Current deployments of OpenShift platform with Kuryr CNI in real OpenStack installations (multi-projects environments) are crashing because of kuryr-controller cannot come to READY state. This is due to inaccurate quota calculations in the readiness process and an unscalable fetching of objects from Neutron API to count and comparing with limits. This commit ensures accurate quota calculation for installation project during the readiness checks and removes the harsh Neutron API calls. It will dramatically speedup readiness checks.
