* Revert "Examples update, add a note for configTime() that only one ntp server is supported by lwip",
fixed in espressif/esp32-arduino-lib-builder#51
This reverts commit 6b1020967a171c549b3d956825fd0d395de9cce0.
* SimpleTime: add NTPoDHCP option and TimeZone env variable
lwip lib bundled with esp32 Arduino supports only one ntp server. Any additional servers set are just silently ignored.
This default is different from esp8266 Arduino core and very confusing. Most of the examples provided uses 3 different ntp servers for redundancy while only the first one is used actually.
Addressing issue #4964
