Create permission for CRUD of holdings sources (Settings > Inventory)

Purpose: To provide a separate permission for CRUD of holdings sources defined as reference records in Settings > Inventory > Holdings > Holdings sources.
When the user is given

• the general view permission for all Inventory settings pages and
• this new permission then the user can view, update, create and delete holdings sources on Settings > Inventory > Holdings > Holdings sources.
