Use Internal Correlation ID values for Kernel Rename Feature (#397)

* Updated kernel rename service to use internal correaltion IDs for external correlation IDs and kernel rename values

* Updated for review comments

* Changed if-condition in generateJSON.cpp to check if string view is empty before calling get_entry
