Link one Clef account to multiple WP users

[lolux]

Users have requested the ability to link one Clef account to multiple WP users (e.g., this WP.com thread).

I think this makes good sense access-control-wise and testing-convenience wise. For example, following common sense networking access controls, it is better access- and auditing-wise to divide administrative tasks and writing/editing tasks between an admin-role and an editor- or contributor-role user.

Before building this functionality into wpclef, we should investigate whether other solutions currently exist, and if so, whether they are sufficient to achieve the desired result (e.g., whether https://wordpress.org/plugins/user-switching/ is compatible with wpclef).

Also, if we build this into wpclef, we'll need to handle the additional complexities involved in mapping multiple users in a multisite network to one Clef account.

My initial tests indicate that the User Switching plugin is fully compatible with Clef 2FA and that the desired functionality is amply provided by this plugin. Thus I recommend holding off for now on building this feature into Clef 2FA.
