Review comment:
This should be moved to the constructor.
If an operator already has a factory, it should be using post constructor
`setProcessingTimeService(...)`. The `#setup(...)` method call before is a big
technological debt - intermediate step on migrating the `AsyncWaitOperator`
from `SetupableStreamOperator` to the factory pattern.
True proper solution would be to remove `SetupableStreamOperator` from the
`AsyncWaitOperator`.
Ditto also in other places.
