Fix #880 Design: 1. A global setting `security.TWO_FACTOR_AUTH`. * To support org-level config, we need to introduce a better "owner setting" system first (in the future) 2. A user without 2FA can login and may explore, but can NOT read or write to any repositories via API/web. 3. Keep things as simple as possible. * This option only aggressively suggest users to enable their 2FA at the moment, it does NOT guarantee that users must have 2FA before all other operations, it should be good enough for real world use cases. * Some details and tests could be improved in the future since this change only adds a check and seems won't affect too much. --------- Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
