file_order_sink should almost be handled like a normal job chain node

Current Situation

We assume we have a job chain with a <file_order_sink .../> configuration.

• The web services ./job_chain/p and ./job_chains/p response an end node with file order sink attributes ("move" and "remove").
  file order sink example

  {
      "name": "example",
      "remove": false,
      "move": "/path/to/archive"
  }
  

• The JobScheduler creates a job /scheduler_file_order_sink which is the job of a "normal" job chain node and in addition it creates a new temporary end node.

So, the web services don't reflect the JobScheduler. In particular the node doesn't have functions in JOC Cockpit such as "unstop job" etc. If the /scheduler_file_order_sink job is stopped then you did't have any options to change this situation.

Desired Behavior

• The web services ./job_chain/p and ./job_chains/p response a "normal" job chain node with an additional end node
  normal job chain node for permanent information

  {
      "name":  "example",
      "nextNode": "fileOrderSinkEnd",
      "errorNode": "fileOrderSinkEnd",
      "job": {
          "path": "/scheduler_file_order_sink"
       },
       "level": 0
  }
  

• The web services ./job_chain and ./job_chains response a "normal" job chain node with "move" and "remove" attributes and an additional end node

  {
      "name":  "example",
      "state": {
          "severity": 4,
          "_text":  "ACTIVE"
      }
       "job": {
          "path": "/scheduler_file_order_sink",
          "state": {
              "severity": 1,
              "_text":  "PENDING"
          }
       },
       "level": 0,
       "remove": false,
       "move": "/path/to/archive"
  }
  

• JOC Cockpit Gui has to consider that a "normal" job chain node can have the new attributes "move" or "remove". In this case the attributes should be displayed instead of the job name "/scheduler_file_order_sink".
• The web services ./jobs and ./jobs/p retain unchanged. The job /scheduler_file_order_sink will not displayed in JOC Cockpit.
