Process classes view should display the processes

Current Situation

Process classes view doesn't display the processes

Desired Behavior

If the user has a role with the job.view.status permission then the processes of a process class should be displayed similiar to the tasks of a job in the jobs view (see screenshot).
This means that each process ...

• generates a new row in the table of the list view under its process class with information

                 {
  			"agent": "http://agentHost:4445",
  			"job": "/path/to/job",
  			"pid": 0,
  			"runningSince": "2017-06-29T09:19:17.054Z",
  			"taskId": "158881"
  		}
  

• get the same task menu like in the jobs view.
