High priority tasks (#661743)

Urgent tasks can now be prioritized, so that they are executed as soon as possible, i.e. in the next available slot. Other scheduled tasks which are waiting for execution will remain waiting until the high priority tasks have been completed. This provides more flexibility for time-sensitive operations which need to take precedence over regular tasks.

When scheduling a task on the Tasks page of the Web Admin Suite, the user can select the High priority checkbox in the Task priority section to prioritize the task. The task will be marked with a red exclamation mark in the task table.

Tasks can also be prioritized when they are started using a script, e.g. by using:

taskDescriptor.setPriority(1)
