Test failures when running on K8s pods or docker containers locally

[v1v]

I'm running tests/scripts/run_tests.sh with the WEBFRAMEWORK=none using the container python:3.8

A similar error for other different python versions: 3.6, 3.7, 3.9 and 3.10

You can reproduce the error with the below command that runs in one of the docker images I've created for testing skaffold:

docker run --rm -ti docker.elastic.co/beats-dev/apm-agent-python-3_10:v6.12.0-19-gdf6fc75d-dirty@sha256:ad548ceef42ed963c373b0b28ab3b3d33ac016e886fe82d2fce5d8443f753783 /bin/bash -c "WEBFRAMEWORK=none tests/scripts/run_tests.sh"

The docker image content:

ARG VERSION
FROM python:${VERSION}
WORKDIR /code
ADD . .
ENV WEBFRAMEWORK=none

[v1v]

I guess the default docker image requires some further configuration as done in the current dockerfile in the tests folder.
