Add debug mode

Description:
    1. Could enable debug mode by adding file: /etc/thermal.d/debugging.
        $ mkdir /etc/thermal.d
        $ touch /etc/thermal.d/debugging
        $ systemctl restart phosphor-pid-control

    2. Could record fans output PWM, chosen temperature, PID/stepwise output PWM in debug mode.

Design:
    1. Create debugging file and restart service to enable debug mode.

    2. Check if debug mode is enabled to output fans output PWM, chosen temperature,
       PID/stepwise output PWM, and so on.

Test Case:
    1. Enable debug mode and check logs: pass
