✨ instrument (opentelemetry) httpx clients

[bisgaard-itis]

What do these changes do?

• Ensure traces are propagated through httpx clients using https://pypi.org/project/opentelemetry-instrumentation-httpx/
• Individual clients are instrumented. The tool actually allows to instrument all clients at once (see link above) but this uses black magic. E.g. if that is done

import httpx
client = httpx.AsyncClient()

produces an instrumented client whereas

from httpx import AsyncClient
client = AsyncClient()

doesn't. Essentially they are mocking the httpx clients. I prefer passing objects around to using black magic.

• One advantage of this approach is that all httpx clients pass through a single fcn so if in the future we want to customize instrumentation and how they handle tracing this should be rather easy.
