* Child process queue workers
- Remove `ShouldBroadcast` in favor of `ShouldBroadcastNow` in `Events\\ChildProcess` namespace
- Implement `QueueWorker::class`
- Add new binding to `NativeServiceProvider::class`
- Fire up workers: iterate through queue worker config in `NativeServiceProvider::configureApp()`

- Test `QueueWorker::up()`, `QueueWorker::down()`
- Test `QueueWorkerFake::class` assertions work as expected

* Prevent attempting to boot workers on CLI calls

* Remove creating workers just by string

Rely on keys of the config array to assert uniqueness of worker aliases

* Allow workers to be instantiated directly by alias

* Fix styling

* Fix tests
