Modify JSON contributions dynamically

[forman]

Is your feature request related to a problem? Please describe.

In my app, I'm using contribution point menus from the contrib module to let extensions contribute menu items.
Menu items must currently provided by JSON entries in the extension's package.json.
I have a top-level menu "View" with a submenu "Tool Views... >".
This submenu should be filled from the contributions to another contribution point, namely toolViews.
Therefore I need to programmatically add (or replace) JSON entries to (or in) the menus contribution point.

Describe the solution you'd like

Possible options

• (1) Support an auto-fill marker in the specific submenus contribution point so the framework can generate the menu entries from contributions of another referenced contribution point.
• (2) Support adding JSON contributions programmatically, e.g., provide a new registerJsonContribution or the like similar to registerCodeContribution .

(1) is more pragmatic and applies to that specific contrib point only
(2) is more generic and flexible

And (2) does not exclude (1).

Decided to let the UI-providing application generate dynamic menus instead of implementing it here.
