mod_http_oauth2: Implement stateless dynamic client registration
Replaces previous explicit registration that required either the
additional module mod_adhoc_oauth2_client or manually editing the
database. That method was enough to have something to test with, but
would not probably not scale easily.
Dynamic client registration allows creating clients on the fly, which
may be even easier in theory.
In order to not allow basically unauthenticated writes to the database,
we implement a stateless model here.
per_host_key := HMAC(config -> oauth2_registration_key, hostname)
client_id := JWT { client metadata } signed with per_host_key
client_secret := HMAC(per_host_key, client_id)
This should ensure everything we need to know is part of the client_id,
allowing redirects etc to be validated, and the client_secret can be
validated with only the client_id and the per_host_key.
A nonce injected into the client_id JWT should ensure nobody can submit
the same client metadata and retrieve the same client_secret
