Current releases of Kubernetes added new metrics that also have the same excessive bucket cardinality. Remove the extra buckets from these metrics. * `apiserver_request_sli_duration_seconds_bucket` * `etcd_request_duration_seconds_bucket` Also reduce the cardinality of apiserver byte histogram metrics. * `apiserver_request_bdy_size_bytes_bucket` This reduces API server metrics in our configuration by about 25%.
