Updated the endpoint for `.set_permissions` to update a user's folder
permissions as well as permissions for a service. User folder
permissions are optional for now, since Admin is not currently passing
this data through.

This lets the admin app pass in a domain to use for email auth links,
so that when it’s running on a different URL users who try to sign in
will get an email auth link for the domain they sign in on, not the
default admin domain for the environment in which the API is running.
by hitting POST /<user_id>/email-code, we create an email two factor
code to send to the user. That email contains a link with a token that
will sign the user in when opened.
Also some other things:
"email verification" (aka when you first create an account) doesn't
hit the API anymore
refactor 2fa code verification and sending to use jsonschema, and share code between sms and email
Die marshmallow die!
