Replace google ping for ntp for usability in locked-down countries

What does this MR do and why?

Currently we open a connection to google.com to check if a user has internet. This changes whether or not we load the creation page in "offline mode" removing the option for server creation. This creates a useability issue for users in countries that do not allow their citizens to access google. This MR will move that request to ntp.org which allows better access for users in locked-down countries while still affording users in countries that allow google a secure source to check internet from.
