Create a tool to bulk update Unique value table.

In user-grid tools we already have tools to identify and manage unique value table like UniqueValueScanner and UniqueValueManager, to update and delete Unique value entries and update them if necessary. 

We faced an issue where some of the entities did not have unique value entry in the table and were not accessible by name. 

This tool is to repair all those entities for which unique value table does not have an entry against name.
