feat: improve tools to include name and add tests (#1693)
This PR makes tool calling aware of the name of the function selected. Fixes: https://github.com/huggingface/text-generation-inference/issues/1657 Thank you @puppetm4st3r for the helpful snippets, large parts of this PR are simply refactors of the code shared 🙏 **opening draft PR because small tweaks are needed before merging
