Simulator Developer Testing IF041_RETAUTH & Creating IF043 files

The files are created under /tru_files/spark/retauth/remote_outbound directory. for e.g "IF041_REAUTH_000001.txt"

In the dev environment setup:

spark.simulator.return.monitor.filepattern=^_IF041_RETAUTH_.*\\.txt$

The the file has to rename in the same directory "_IF041_REAUTH_000001.txt". The file will
be processed and stored under the /tru_files/spark/retauth/local_archive/ directory.

The Simulator will pick the file retauth and create a return file which is "IF043_RETURN_000001.txt" (example) and process the returns and archive
the file in  /tru_files/spark/return/local_archive/ directory.
