Add a process class editor to JOC Cockpit

Current Situation

• Process classes contain references to Agents by use of the Agent URL.
• Therefore the contents of a process class almost never is the same in a non-production environment and in a production environment. This is the reason why users are discouraged to copy process classes between environments, but instead to modify process classes per environment.
• Such modifications of a process class require use of the JOE job editor. However, in a production environment users might not have direct access to job-related configuration files, i.e. they cannot directly modify process classes in a production environment.

Desired Behavior

• Users want to modify the contents of a process class with the JOC Cockpit GUI (similar to what is available from JOE):
  • modify the max_processes attribute value which is the basic function for JS-1784,
  • modify the cluster type (first, next),
  • modify the list of Agent (sequence of Agents, Agent URLs).
• The editor includes CRUD functions to add, update and remove process classes.
• Permissions should be in place to allow access to the operation to modify process classes.
