// Node status update frequency and retry count.
// nodeStatusUpdateFrequency specifies how often kubelet posts node status to master.
// Note: be cautious when changing the constant, it must work with nodeMonitorGracePeriod
// in nodecontroller. There are several constraints:
// 1. nodeMonitorGracePeriod must be N times more than nodeStatusUpdateFrequency, where
// N means number of retries allowed for kubelet to post node status. It is pointless
// to make nodeMonitorGracePeriod be less than nodeStatusUpdateFrequency, since there
// will only be fresh values from Kubelet at an interval of nodeStatusUpdateFrequency.
// 2. nodeMonitorGracePeriod can't be too large for user experience - larger value takes
// longer for user to see up-to-date node status.
// 3. nodeStatusUpdateFrequency needs to be large enough for Kubelet to generate node
// The constant must be less than podEvictionTimeout.
// 2. nodeStatusUpdateFrequency needs to be large enough for kubelet to generate node
// status. Kubelet may fail to update node status reliablly if the value is too small,
// as it takes time to gather all necessary node information.
