Refactor check-dummy.sh to add options for warning, critical and unknown status
This commit refactors the check-dummy.sh script to include options for warning, critical and unknown status. The script now accepts the following command line arguments: --ok (default), --warning, --critical and --unknown. The exit codes have also been updated to reflect these new statuses.
