Update notes for submitted changes

* There are some StatsOracle enhancements: - The UVE REST API will show the stats recorded against UVEs.   This will only show up for UVEs that currently exist (are not deleted)   It will not show up for multi-UVE gets - only when retriving a single UVE   Also, the stats will not be returned if Source-Filter or Module-Filter is used. - Adding support in Vizd for recording prefix-suffix type tags.   Support has not been added yet in QE and in the viz.sandesh table schemas   for doing WHERE on prefix-suffix tags.
