[ASTERIXDB-1949][FUN][ING] Function usage check refactoring in feed

- user model changes: no
- storage format changes: no
- interface changes: yes
   Removed several interefaces for maintaining reference count.
   Added getFunctions and getFeeds method for MetadataNode.

Details:

1. Change the usage check from reference count to scan feed connections
   in all dataverses.
2. Add test case for drop dataverse which has function that is being
   used in other dataverse. This operation should be blocked.
3. Fix small bug in apply function metadata which the function dataverse
   was not recorded properly.
