Accept or reject a guest account that is waiting for a sponsor’s approval.
Requires a guest self-registration page that has been configured for sponsor confirmation.
A common filter for /guest to query accounts needing sponsorship is: {"register_token":{"$ne":""},"register_token_confirmed":0}
If guest_register is not the sponsor-enabled self-registration, pass the registration page name as gsr_id.
