/**
* A test NeoPass server! This is a very lean, hacky implementation, designed
* to just see the basic OAuth interactions Work At All.
*
* This server is an `oauth2-mock-server` instance that's easy to spin up and
* have perform OAuth for us. We give it a hardcoded development-only key, and
* it just auto-grants permissions!
*
* It slightly differs from the NeoPass spec, in that it uses different paths
* for its endpoints, but that's okay: DTI will use OpenID's "discovery"
* feature to discover those endpoints via a single well-known path, without
* needing them hardcoded.
