Added new SQL function GET_INDEX_SIZE_BY_PREFIX

Summary: **Motivation** Core Data Demand Efficiency team wants to track physical size of the assoc types and fbtypes, as well as existing logical size. Tracking physical size of the specific assoc/fb types is not available as of now. **Change** Added the new function GET_INDEX_SIZE_BY_PREFIX which returns the index size by prefix. Currently we support only numeric keys. Reviewed By: yizhang82 Differential Revision: D27419569 fbshipit-source-id: 84604ac03bd
