Modify Entity Suggestion support and Add Profile Suggest support

- Added new AutocompleteMatchType for the two, and additionally for personalized and infinite suggestion.
- Added logging for the new suggestion types.
- Annotation for entities is now used as description in the match. This allows multiline rendering in mobile easily.
- Profile suggestions also look like entity suggestion, and use title, annotation and query fields in response.
