BUG: ManualSchedulerBuilder Does Not Use Provided Scheduler Listeners

[EarthCitizen]

Expected Behavior

ManualSchedulerBuilder passes provided SchedulerListeners to the constructor of ManualBuilder.

Current Behavior

When calling .build() on ManualSchedulerBuilder, it does not pass the provided SchedulerListeners to the constructor. Instead, it passes in a hard-coded list that contains StatsRegistryAdapter.

The best way to do automated testing is to use ManualScheduler, but as a result of the above issue, it is not possible to take advantage of ScheduleListeners because they cannot be tested with ManualScheduler.

Additionally, trying to use ManualScheduler.registerSchedulerListener() results in an unsupported operation exception because the unlying list is unmodifiable.

Also cannot bypass constructor and create my own ManualScheduler because its constructor is package private.

Currently having to resort to some reflection to add the listeners.
