Adding caching API. The API is registered as a module.
Adding cache.py
Add copy page functionality in the editor

 - Added a "copy page" button to make a duplicate of an existing page in the
   editor and use it for another page. This helps for users to easily duplicate
layout/styles of an existing page and create a new page out of it.
/pages API was not showing id of a page, adding id in the response.
