Package init installs GrabBeforeEach and GrabAfterEach as callbacks for gathering data before and after a test.

APICallToPerfData transforms APIResponsiveness to PerfData.

GetDefaultKubeletLatencyMetrics calls GetKubeletLatencyMetrics with a set of default metricNames identifying common latency metrics.

GetKubeletLatencyMetrics filters ms to include only those contained in the metricNames set, then constructs a KubeletLatencyMetrics list based on the samples associated with those metrics.

GetKubeletMetrics gets all metrics in kubelet subsystem from specified node and trims the subsystem prefix.

GrabKubeletMetricsWithoutProxy retrieve metrics from the kubelet on the given node using a simple GET over http.
