Spring Security AuthorizationRequestRedirectFilter needs a way to customize errors

Summary

Currently sendRedirectForAuthorization can throw an IllegalArgumentException if the client registration is not found. This means there is a big stacktrace provided on the screen by default. We should allow some strategy to be used for handling the error (i.e. rendering an error page, forwarding to the error page, etc).

This issue is no longer valid as IllegalArgumentException is not thrown and instead response.sendError() is used.
