If it is set, the client must itself reset or disable rtc_wdt in their code (app_main()).
Otherwise rtc_wdt will be disabled before calling app_main function.
If this option is set, the ESP-IDF app must explicitly reset, feed, or disable the rtc_wdt in
the app's own code.
If this option is not set (default), then rtc_wdt will be disabled by ESP-IDF before calling
the app_main() function.
Use function rtc_wdt_feed() for resetting counter of rtc_wdt.
Use function rtc_wdt_disable() for disabling rtc_wdt.
