Simplify the code of jobs that do not care about titles and removes the direct Title dependency from JobQueue. Remove getTitle() from IJobSpecification itself. Move all the Job::factory calls into a single JobQueue::factoryJob() method. Depends-on: Iee78f4baeca0c0b4d6db073f2fbcc56855114ab0 Change-Id: I9c9d0726d4066bb0aa937665847ad6042ade13ec
