mod_pubsub_post: Restructure authentication and authorization (BC)
This deprecates the default "superuser" actor model and makes the
default equivalent to the previous "request.id".
A single actor and secret per node is supported because HTTP and
WebHooks don't normally include any authorization identity.
Allowing authentication bypass when no secret is given should be
relatively safe when the actor is unprivileged, as will be unless
explicitly configured otherwise.
