      * Reduce apiserver metric cardinality
      
      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%.
