Manage object references

Current Situation

• When referencing JobScheduler objects, e.g. a job referencing an Agent Cluster, then the name of the referenced object, i.e. the Agent Cluster, is used.
• If the name of the referenced object changes, then this change is not reflected with the object, e.g. the job, that holds the reference.

Desired Behavior

• If the name of a referenced object changes then all objects that hold a reference to the changed object should reflect the change.
• This applies to the following objects and references:
  • job: Agent Cluster, Process Class, Lock, Monitor, Schedule
  • job chain: Agent Cluster, Process Class, Job

Maintainer Note

• This feature is dismissed as a feature-complete implementation is out of scope.
• Basically the feature requests JS-1876, JS-1858 and JOC-852 are related. 
• The risks of modifying the 1.13 code base in this scope are considered too high.
• Instead, the functionality to operate on folders and to use object references in the job inventory as requested from the indicated issues is available with JS7 branch 2.0
