Merged Imre Farkas requested to merge if-212312-forti_authenticator into master

What does this MR do?

Adds FortiAuthenticator as OTP validation method. It refactors existing OTP code validation to Users::ValidateOtpService. The feature is currently behind the forti_authenticator feature flag. If the feature flag is enabled for the user, the OTP verification goes through FortiAuthenticator instead of Devise. User flow is not changed in this MR, the same views are presented to the user as previously.
