Perform an upstream refresh during downstream refresh for OIDC upstreams
- If the upstream refresh fails, then fail the downstream refresh - If the upstream refresh returns an ID token, then validate it (we use its claims in the future, but not in this commit) - If the upstream refresh returns a new refresh token, then save it into the user's session in storage - Pass the provider cache into the token handler so it can use the cached providers to perform upstream refreshes - Handle unexpected errors in the token handler where the user's session does not contain the expected data. These should not be possible in practice unless someone is manually editing the storage, but handle them anyway just to be safe. - Refactor to share the refresh code between the CLI and the token endpoint by moving it into the UpstreamOIDCIdentityProviderI interface, since the token endpoint needed it to be part of that interface anyway
