Add permission configuration [allow/deny] per extension

The user should have the power to allow or deny some permissions access for the installed extension or at least approve such permissions before the application start running, like android or mac apps.


The issue names no files, tests, or entry points; begin by locating how installed extensions and their permissions are represented and approved. Done means the project has a defined allow/deny or approval flow for extension permissions before the application runs, with coverage for the supported behavior.
