Kubernetes: Backported Fixes and a Cleanup Sprint

A grpc transport bug that could hang the API server on etcd reads got backported fixes across two release branches, while a wave of smaller PRs cleaned up scheduler behavior, HPA scaling logic, and long-deprecated polling code. Several contributions carry AI-assisted disclosures, a trend worth watching as review load shifts.

The root issue: a connection recycling bug in grpc's HTTP/2 client could strand in-flight…

Second theme: correctness fixes in scaling and scheduling logic. The horizontal pod autoscaler saw a subtle bug fixed in PR 141134, where status replicas leaking into spec caused unwanted scale-ups during rolling updates when using average-value metrics. Separately, PR 141118 closes a gap in dynamic resource…

Third theme: maintenance and technical debt. Client-go got a sweep of deprecated polling calls replaced with context-based alternatives in PR 141135. Test suites got trimmed too - orphaned MySQL, Cassandra, and Zookeeper e2e dependencies were dropped in PR 141129, and several storage and DNS tests had incorrect…

Smaller but notable: kubectl's PrintObj errors are no longer silently swallowed, fixed in PR 141116, and the eviction manager in kubelet now retries dedicated image filesystem checks…
