Solution description

This PR enables the use of 2FA in servers above v41. It depends on this PR SDK side.

When a user activates 2FA the app will detect the failure produced by a login attempt on a 2FA-enabled user and will add a field asking for 2FA code to that user.

The 2FA requires the cookie to be present after that login. So when the login expires (this is e.g. when its been a while since the user didn't login) the sync attemps will fail. It is important to note that, effectively, this means that when a user activates its 2FA, the user needs to be trained in the different from a sync perspective, as the app will only sync its metadata/data after a login is done. It's then important that the user knows that without a login, the data that was not synced won't be synced to the server before the next login.
