- Avoid GCE API calls when initializing GCE CloudProvider for Kubelets. ([#90218](https://github.com/kubernetes/kubernetes/pull/90218), [@wojtek-t](https://github.com/wojtek-t)) [SIG Cloud Provider and Scalability]

* GCE provider: Create TargetPool with 200 instances, then update with rest ([#27865](https://github.com/kubernetes/kubernetes/pull/27865), [@zmerlynn](https://github.com/zmerlynn))
* GCE provider: Limit Filter calls to regexps rather than large blobs ([#27741](https://github.com/kubernetes/kubernetes/pull/27741), [@zmerlynn](https://github.com/zmerlynn))
