Overprovisioning Factor

Priority levels and localities are considered overprovisioned with :ref:this percentage <envoy_v3_api_field_config.endpoint.v3.ClusterLoadAssignment.Policy.overprovisioning_factor>. Envoy doesn't consider a priority level or locality unavailable until the fraction of available hosts multiplied by the overprovisioning factor drops below 100. The default value is 140 (in percentage, which means 140%), so a priority level or locality will not be considered unavailable until the percentage of available endpoints goes below 72%.
