Navigation from the child process instance to the parent process instance using Process Diagram

Account: Enel Servizi Srl, 1481946

Goals
Once the user is under Diagram tab for a given process instance, it should be able to navigate to the parent instance, or subprocess instances for that given process instance.

Motivation
The customer uses extensively reusable sub-processes for error handling and to split large flows in more manageable units. They request navigation links between parent and child processes in Diagram tab to easily manage such.

Expected behavior
UX did the proposal available at: https://marvelapp.com/4a5332f/screen/64946877 what should be followed, which demonstrate:

• A new menu should be created on top of Node Actions, containing links to the direct Parent process if it exists (otherwise it should be as "none") and links to subprocess instances if it has any.
• Parents and subprocess should be identified by its names as clickable, and by their IDs (not clickable)

Out of Scope

• Open subprocess diagram when clicked over the subprocess task in the SVG (this feature should delivered by BAPL-1501)

Current behavior

• There is no navigation from parent to child subprocess in Diagram tab

Testing

• Unit test coverage according to repository thresholds.
• Limited scope Selenium tests assessing basic functionality of the feature.

Not mandatory, but nice to have (if time allows)
UX recommended a Full Screen Toogle for the Process Diagram
