ITD27M01 9cdd1c8112 Ensures accurate quota calculation during the readiness checks
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.

This function is also discoverable via the 'kuryr' entry point under

The purpose of this is to allow tools like the Oslo sample config file
