Functions

func AddLabelToLabelSet 

func AddLabelToLabelSet(labelSets [][]prompb.Label, lbl LabelDesc) [][]prompb.Label

func JitterUp 

func JitterUp(duration time.Duration, jitter float64) time.Duration

JitterUp adds random jitter to the duration.

This adds or subtracts time from the duration within a given jitter fraction. For example for 10s and jitter 0.1, it will return a time within [9s, 11s])
