Automatic merge from submit-queue. Manual cherrypick of #65034 to 1.9: make json serializer case sensitive fixes partially https://github.com/kubernetes/kubernetes/issues/64612 This PR imports the latest jsoniterator library so that case sensitivity during unmarshalling is optional. The PR also sets Kubernetes json serializer to be case sensitive. **Release note**: ```release-note ACTION REQUIRED: Kubernetes JSON deserializer is now case-sensitive to restore compatibility with pre-1.8 servers. If your config files contains fields with wrong case, the config files will be now invalid. ``` /sig api-machinery /kind bug /assign caesarxuchao liggitt thockin sttts mbohlool Kubernetes-commit: f4cf484c2cb6056e28fb9759a3c913be3eed990a
