feat(command): implement command execution for service monitoring

Add functionality to parse and execute commands for adding/removing service monitors and shutting down the watchdog. The ExecuteCommand function now handles "monitor.add", "monitor.remove" and "watchdog.shutdown" commands by interacting with the monitor package and system operations.
