Tracking verification of conditions for bumping go1.21 on release branches:

• ~2023-11-01: 3 months after go 1.21 release (ETA 2023-08-01)
• ~2024-01-15: 1 month after Kubernetes 1.29 release on go1.21 (ETA 2023-12-15)
• no regressions relative to go 1.20 known to impact Kubernetes: there are no regressions that are fixed in go1.21.7 (yet to be released and consumed by Kubernetes) that are known to impact Kubernetes (ref)
• pass unit and integration tests with both go 1.21 and the original go version for the release branch
  • 1.26: demonstrated in: [prep go1.21 bump] Test 1.26 release branch with go1.21 kubernetes#122783
  • 1.27: demonstrated in: [prep go1.21 bump] Test 1.27 release branch with go1.21 kubernetes#122784
  • 1.28: demonstrated in: [prep go1.21 bump] Test 1.28 release branch with go1.21 kubernetes#122785
• any behavior changes in go 1.21 are mitigated to preserve existing behavior without requiring action by Kubernetes end-users
