```
OptionalInt calculatePriority(TaskSummary taskSummary)
```
    Determine the priority of a certain Task during execution of TaskService.createTask(Task) and TaskService.updateTask(Task). This priority overwrites the priority from Classification-driven logic.
    The implemented method must calculate the priority efficiently. There can be a huge amount of Tasks the SPI has to handle.
    The behaviour is undefined if this method tries to apply persistent changes to any entity.
    This SPI is executed with the same UserPrincipal and GroupPrincipal as in TaskService.createTask(Task) or TaskService.updateTask(Task).
    
    Parameters:
    
    taskSummary - the TaskSummary to compute the priority for
    
    Returns:
    
    the computed priority
