// wrapTimer keeps track of the timing of a async operation and emits
// a event on the given eventBus once the operation is complete
//
// the returned function is designed to stop the timer and emit the event
//
// Usage:
// Define the timer function. It can be done once per class.
// this.timer = (action: string) =>
// metricsHelper.wrapTimer(eventBus, DB_TIME, {
// store: 'client-feature-toggle-read-model',
// action,
// });
//
// Before performing an operation, start the timer:
// const stopTimer = this.timer(`timer-name`);
// // perform operation and then stop timer
// stopTimer();
