Event SetStatisticsUpdatePeriod

Control request to set the interval (seconds) between query statistics updates, i.e. how often the "Correlator Query Statistics" and "Cluster-Wide Query Statistics" dataviews are updated.

This is set by specifying two floats, the periods of time between: the instance sending per-instance update and the workers sending per-worker updates.

Constant summary
`string`	`NAME := "SetStatisticsUpdatePeriod"` Configuration name of statistics update period.

Member summary
`float`	`instanceUpdatePeriod` Interval (seconds) between per-instance updates.
`float`	`workerUpdatePeriod` Interval (seconds) between per-worker updates (for meaningful statistics it is recommended to set this to a value smaller than instanceUpdatePeriod).

Action summary
`boolean`	`isDisabled()` Get whether statistics are disabled. Sending in an event with either field set to zero will disable query statistics.
