Add filtering, ordering and permissions management capabilities for Functions

[giancarloromeo]

As discussed with @giancarloromeo :

For the Voyager sprint, wrt backend:

• WVG needs to implement in repository/service layer: set_permissions (already exist in repo), remove_permissions, search by name/description for list_functions, sort by name/created/modified in list list_function
• @giancarloromeo will then expose these in webbrowser REST API
