EAP-MSCHAPv2 support

Seems that Fortinet is moving towards EAP-MSCHAPv2 for authentication.

[IKEv2 dialup IPsec tunnel with RADIUS server authentication and FortiClient](https://community.fortinet.com/t5/FortiGate/Technical-Tip-IKEv2-dialup-IPsec-tunnel-with-RADIUS-server/ta-p/191040)

Is in the roadmap supporting it?
