Handle multiple actor for same job case

[brandonpille]

We currently expect jobs to be for one specific actor. But it could be that two actors are handeling the same jobs. We need to decide how to handle that. Possibilities (just thinking here):

• We make all actors handle the job
  • We mark the job as completed if all actors handled the job
  • We mark the job as completed if one of the actors handled the job
  • We mark the job as completed if most actors completed the job
  • We allow the choice for prior 3 methods via the job description
• We make one actor handle the job which could be:
  • the first in the list
  • the fastest
• We introduce priorities in actors (highest priority gets to execute the job)
