Make ProcessScheduleServiceTest deterministic

[deepthidevaki]

Description

Migrated ProcessScheduleServiceTest to use ControlledActorScheduler.
Except two tests shouldNotExecuteScheduledTaskIfNotInProcessingPhase and shouldExecuteScheduledTaskInProcessing, all other tests are deterministic and does not rely on timeouts. These two tests repeatedly submit tasks. So we cannot use workUntilDone to wait for all tasks to be executed. So they rely on timeouts and hopes that the expected task is executed within the timeout.

👍 Very nice! Can you share the modification to our team about the new helpers in ControlledActorScheduler and how they can be used, esp. when using timers?

I guess we should also backport this? Or is 8.1 not affected? The ControlledActorScheduler changes might be useful even in 8.0 as well, even if we don't have the engine refactoring parts.

This should be backported. Atleast some of these tests are already in 8.1.
