ST / Mbed 2 deprecated NTPClient_HelloWorld

NTP client app setting system time and X-NUCLEO-IDW01M1 Wi-Fi board time connecting to internet NTP UTC time server.

Dependencies:   NTPClient NetworkSocketAPI X_NUCLEO_IDW01M1v2 mbed

Fork of NTPClient_HelloWorld by ST Expansion SW Team

Example of retrieval of current time using an NTP server. Time is then used to perform a TLS secure connection to https://mbed.org.
The application is meant to be used with mbed OS 2 ("Classic") only (no mbedOS 5 support).
