- To better support having multiple downstream providers configured,
the authorize endpoint will share a CSRF cookie between all
downstream providers' authorize endpoints. The first time a
user's browser hits the authorize endpoint of any downstream
provider, that endpoint will set the cookie. Then if the user
starts an authorize flow with that same downstream provider or with
any other downstream provider which shares the same domain name
(i.e. differentiated by issuer path), then the same cookie will be
submitted and respected.
- Just in case we are sharing the domain name with some other app,
we sign the value of any new CSRF cookie and check the signature
when we receive the cookie. This wasn't strictly necessary since
we probably won't share a domain name with other apps, but it
wasn't hard to add this cookie signing.

Our unit tests are gonna touch a lot more corner cases than our
integration tests, so let's make them run as close to the real
implementation as possible.

We want to run all of the fosite validations in the authorize
endpoint, but we don't need to store anything yet because
we are storing what we need for later in the upstream state
parameter.

- Add a new helper method to plog to make a consistent way to log
expected errors at the info level (as opposed to unexpected
system errors that would be logged using plog.Error)

Also move definition of our oauth client and the general fosite
configuration to a helper so we can use the same config to construct
the handler for both test and production code.

Previously we were injecting the whole oauth handler chain into this function,
which meant we were essentially writing unit tests to test our tests. Let's push
some of this logic into the source code.

Does not validate incoming request parameters yet. Also is not
served on the http/https ports yet. Those will come in future commits.
