A work queue is used to start workloads asynchronously. The workload itself always run once at a time. Use cases: * parsing ingress: the ingress parser and config builder is a workload which runs when the k8s state changes * acme signer: a v0.9 feature, sign a new certificate is a workload which runs when a new certificate need to be issued
Rate limit is a mandatory argument on `NewQueue()`, if greater than 0 will configure a rate limiting control to call sync. Every single call to `Add()` is rate limited before calling `sync()`. Use `Notify()` instead if a single/global rate limit should be used instead one per added item.
