Andrew Lytvynov 6d8f778157 mfa: add WithMFA to session-related audit events (#5833)
* mfa: put device UUID in MFAVerified cert extensions

Instead of just a bool, add the device UUID. This will be used in audit
events when a session is started using MFA-issued certs.

* Add WithMFA to session-related audit events

Also extract a common function for parsing SSH certs.
