JobScheduler logs information on what agent a task is executed

Current Situation

• JobScheduler can run jobs on different agents but the end-user logs (task log, order log) don't show on which agent a job is run
• Finding out where a job is run has become even more difficult since JS-1451
• The Log message "SCHEDULER-842 Task is going to process Order..." always prints the address of the master JobScheduler

Desired Behaviour

• The Log message "SCHEDULER-842 Task is going to process Order..." should print the addres of the JobScheduler or Agent on which the task is executed
• The task log should also include a message about JobScheduler or Agent on which the task is executed.
