Display job instruction label instead of position

Current Situation

• Controller and Agents specify specify the order position using a syntax that denotes the position in the workflow's graph.
• JOC Cockpit offers labels in some places such as order logs and task logs and in other places displays the position.

Desired Behavior

• Wherever possible the GUI should display the label instead of the position.
  • As of now labels are mandatory for job instructions only. However, user can add labels to any workflow instructions.
    • The current improvement applies to labels of job instructions
    • This does not apply to labels of other workflow instructions that are subject to future improvement.
  • If a label is available then it is displayed instead of the position. The position is made available from a tooltip for the label.
  • If no label is available then the position is used for the related column "Label" in the GUI.
  • In no situation both label and position should be displayed.
• For any views that are based on inventory information the label should be displayed.
  • History View including Order History and Task History
  • Workflows View with sub-view for Order History and Task History
• For views that are not based on inventory information the position is displayed. No label is displayed.
