// GarbageCollector.Sync(client, period, stopCh):
// wait.Until() loops with `period` until the `stopCh` is closed :
// wait.PollImmediateUntil() loops with 100ms (hardcode) util the `stopCh` is closed:
// GetDeletableResources()
// gc.resyncMonitors()
// controller.WaitForCacheSync() loops with `syncedPollPeriod` (hardcoded to 100ms), until either its stop channel is closed after `period`, or all caches synced.
//
// Setting the period to 200ms allows the WaitForCacheSync() to check for cache sync ~2 times in every wait.PollImmediateUntil() loop.
