Fetch requested by user for a change record using getRefRecord() (#1500)

* Create GetRecordRequestedBy_Soumyadeep.js

This piece of code typically for the background script would fetch the change request record whose sys_id has been provided and then  through the getRefRecord() it would fetch the requested by user and print its field values for "user_name" and "email".

* Create Readme_Soumyadeep.md

This script will glide for a particular record whose sys id has been provided
It will fetch the record and then use getRefRecord() to fetch the requested by user details.
If the user is a valid record, then it will fetch the user_name and email.
