Summary

A new package i.e org.openelisglobal.common.userId was created and a new class that contains the only one method i.e protected String getSysUserId was created
This class acts as a super class to all the classes that were inheriting the BaseRestController class and it also implements the IActionConstants interface

Thanks @Ariho-Seth for attempting to work on this.
I dont think the issue required renaming BaseRestController to SysUserId .
it only required removing getSysUserId from any controller and use the reusable method from the baseClass
