Meridix Two Factor Authentication provider configuration

From the October release 2020 Meridix support two factor authentication through e-mail (SMTP), OTP (Authenticator apps such as Microsoft Authenticator or Google Authenticator) or SMS (twilio (SMS SaaS vendor) or SMPP).

The following providers are available: otp, twilio and email and the configuration is done through the standard property provider system. The 2FA can be configured on system, reseller or customer level but not on the user level.
The system can and should have at least two providers set (not required). To disable 2FA completely do not set any providers at all.
