Port Google Login Authenticator To Drupal 8

The Google Login Authenticator Module adds an extra layer of security to the Drupal login architecture. The plugin no longer works in Drupal 8 because of the architecture change between Drupal 7 and 8, Drupal 8 being more Symfony rich. The aim of this project is to port the the module over to Drupal 8 as a plugin for Two Factor Authentication Module which works in Drupal 8. Additional functionality like checking for time discrepancy will also be added in this port.
