This adds a shortDescription property to HTTPClientError which provides a short
description of the error without associated values.

This is useful for e.g. metric labels which should not contain dynamic, potentially unbounded, associated values.

One small change :) Since this is a public API change, let's get @Lukasa on here as well.
