Resolves: #463774

Summary: index files for database should be deleted when db is deleted.
Fix Description: The callback ldbm_instance_post_delete_instance_entry_callback
is called when the backend instance is removed.  In the callback, there was a
code to cleanup the primary db (id2entry.db#), but no other index files nor the
instance directory.  Also, the code included a bug to get the instance
directory path.  The proposed code gets the right instance directory path and
cleans up all the files in the directory, then removes the backend instance
directory.
