New Pika 0.28b0 instrumentation requires packaging, not declared in transitive dependencies

[phillipuniverse]

Describe your environment

I just upgraded opentelemetry-instrumentation-pika in my environment to 0.28b0. The commit at 26aa17f and #837 introduced this line:

from packaging import version

This results in the following in my environment:

ModuleNotFoundError: No module named 'packaging'

I assume the problem is that I don't have any of the setuptools or related dependencies in my environment since I'm deploying a webapp on Docker. But I would have expected at least a new transitive dependency or something in order to use this functionality.

My environment is Python 3.7.12 and I am using the Docker image FROM python:3.7.12-buster.

This fortunately doesn't break my whole environment, but I do get the ModuleNotFoundError: Instrumenting of pika failed message.

The fix is to add packaging into your venv.
