v1.9.0-preview5

See the changelog for details.

In this pre-release, we introduced resourceQuotaEstimator (PR-4566) plugin for the accurate scheduler-estimator. It is an alpha feature, the user can enable it by passing the feature gate in the estimator command line --feature-gates=ResourceQuotaEstimate=true
Once this feature is enabled, the accurate scheduler-estimator will estimate the number of workload replicas allowed by the resource quota.
We only
support compute resources (CPU/memory) and extended resources (like GPU) in this plugin
support priorityClass in the quota scope
User needs to explicitly specify the priorityClassName in the podTemplate of Deployment, Statefulset, Job, and custom-resource-interpreter.
