Fosite v0.42.0 introduced a new RevokeRefreshTokenMaybeGracePeriod()
interface function. Updated our code to support this change. We didn't
support grace periods on refresh tokens before, so implemented it by
making the new RevokeRefreshTokenMaybeGracePeriod() method just call
the old RevokeRefreshToken() method, therefore keeping our old behavior.
This will allow us to store custom data inside the fosite session
storage for all downstream OIDC sessions.

Before this change, we used the `fosite.DefaultOpenIDConnectClient{}` struct, which implements the `fosite.Client` and `fosite.OpenIDConnectClient` interfaces. For a future change, we also need to implement some additional optional interfaces, so we can no longer use the provided default types. Instead, we now use a custom `clientregistry.Client{}` struct, which implements all the requisite interfaces and can be extended to handle the new functionality (in a future change).
There is also a new `clientregistry.StaticRegistry{}` struct, which implements the `fosite.ClientManager` and looks up our single static client. We could potentially extend this in the future with a registry backed by Kubernetes API, for example.
This should be 100% refactor, with no user-observable change.
