configuration documentation needs updating

[Alistair Coles]

Some of the documentation of configuration options [1] appear to be out of date. For example, I have seen in code changes that auth_host, auth_port are deprecated and replaced by identity_uri, which isn't mentioned in this doc [1].

[1] doc/build/html/middlewarearchitecture.html#configuration

The documentation absolutely needs to be updated.
