We currently have two pages, which don't gel together particularly well: https://docs.opsmanager.mongodb.com/current/core/two-factor-authentication/, and https://docs.opsmanager.mongodb.com/v1.6/tutorial/manage-two-factor-authentication/

We should reorganize these into five pages: a 2FA overview doc, which would retain the conceptual material (and describe the different levels), and four tutorials that would hold the procedures:

• Enable 2FA for Ops Manager ( mms.multiFactorAuth.level=REQUIRED | =OPTIONAL | =REQUIRED_FOR_GLOBAL_ROLES)
• Disable 2FA for Ops Manager ( mms.multiFactorAuth.level=OFF)
• Configure 2FA for a User Account (working title – covers the setting up 2FA on one's device / SMS / etc., and generating backup codes).
• Reset a User's 2FA Account

Make sure you handle the Ops Manager-only stuff
