Use "localhost exeption" to create users for at least ephemeralForTest

[hasezoey]

Thanks to #670 (comment) i now know that it is possible to create users while auth is active, even in ephemeralForTest and everything through the mongodb nodejs driver, so this issue is tracking the implementation of this.

Mongodb Documentation: Localhost Exeption
TL;DR: (from Create the user administrator Note)

You can create the user administrator either before or after enabling access control. If you enable access control before creating any user, MongoDB provides a localhost exception which allows you to create a user administrator in the admin database. Once created, you must authenticate as the user administrator to create additional users.
