Parameters:
* cmd (list): command to be executed with its arguments.
Returns:
psutil.Popen: Object view of the process
Notes:
* The command is executed by the Popen function of the psutil module.
* Since the command is run as a daemon, it does not block the execution of the script.
* stdout is captured and forwarded to odpy.proclog_logger.
* stderr is captured and forwarded to odpy.proclog_logger.
