🐛 Bug Report: OpenAI spans are not always started as current span

Which component is this bug for?

OpenAI Instrumentation

📜 Description

When having httpx instrumentation enabled, the POST span to the chat completions endpoint does not have openai.chat as a parent.

#1541 reports a similar behavior for the Langchain instrumentation.

👟 Reproduction steps

• Use opentelemetry-instrumentation-httpx and opentelemetry-instrumentation-openai
• Send a chat completions request

👍 Expected behavior

The POST request should have openai.chat as a parent.

👎 Actual Behavior with Screenshots

The httpx span and the openai.chat span have the same parent.

👀 Have you spent some time to check if this bug has been raised before?

• I checked and didn't find similar issue

Are you willing to submit PR?

Yes I am willing to submit a PR!

Start with the referenced chat_wrappers.py and embeddings_wrappers.py sections, comparing how each span is made the current active span. Reproduce the issue with httpx and OpenAI instrumentation while sending a chat completions request. Done means the httpx POST span has openai.chat as its parent, rather than sharing its parent.
