SNTP manual interval request in the application (IDFGH-337)

[Trubochkin]

The SNTP component provides public methods sntp_init and sntp_stop, but does not provide the method sntp_request publicly. Also, I see that request interval is set by define. I need to set the request interval manually in my application. How can I do this?

@Trubochkin currently LWIP SNTP doesn't provide API to manually set the polling interval. However, you can change the polling interval by changing SNTP_UPDATE_DELAY in lwipopts.h, the default polling interval is 3600000 milliseconds.

I'm just doing re-initialization https://github.com/Trubochkin/BLE-WiFi-Gateway/blob/e19b131202b30d53837ea74e309dee601084ee8e/components/f_sntp/f_sntp.c#L93

@Trubochkin You have an error in your code, you're busy waiting for sntp_enabled (probably a zealous ';' here). You probably need #2349 to be fixed too to avoid waiting 500ms for nothing, and instead be informed when the time has been changed.

Hi @Trubochkin! We will add the Kconfig option to change SNTP_UPDATE_DELAY. It will be merged soon.
