Add a way for admins to disable 2FA for a user

[MikeAlhayek]

Is your feature request related to a problem? Please describe.

There are times where a user can no longer use 2FA and has no more access to the recovery codes. And admin should have a way to disable 2FA from the Users admin UI.

Also when the Two-Factor Email Method feature is enabled, it may be helpful to add an option to email the user a single recovery code to login with.

I think we should Add a new Actions button next to the user and move both Delete and Edit Password into the Actions button. Additionally, inject Disable two-factor item in the Actions menu when Two-Factor Authentication Services feature is enabled.

And when the Two-Factor Email Method feature is enabled, add another item to allow sending the user a single recovery code when the user has a confirmed email.

A single-use recovery code would be great, though I think a simple disable 2FA is also enough: At this point, you as an admin should do whatever specific to the use-case you can do to make sure the user is legit. I'm not sure if another e-mail helps too much here.
