Description

In Haystack 3.0, we'll introduce support for async tools.

Given this, it should be possible to simplify this integration, where much work is done to bridge sync/async.

If we end up implementing tool lifecycle handling (https://github.com/deepset-ai/haystack-private/issues/426), this should be adopted in this component, leading to further simplification.
