auth: request.go diff

Add Client updating from the API. Add a handler to update Clients using the API. Add a helper that will decode a request for us based on its Content-Type header. Change the ClientChange.Validate function to return as many errors as possible, as opposed to just the first error it encounters. Update the ClientChange.Validate tests to take advantage of the new signature.
