Using bzt with gatling - missing packaging in requirements

[wloboz]

Python module packaging is not in requirements.txt, yet it is needed to run bzt with gatling executor from a docker container.

Run docker build . in a folder with a basic dockerfile (see below). It will fail with ERROR: ModuleNotFoundError: No module named 'packaging'. If you use pip to install packaging, for example by replacing RUN pip install bzt==$TAURUS_VERSION with RUN pip install bzt==$TAURUS_VERSION packaging, it will work fine.

Example Dockerfile:

FROM ubuntu:22.04

RUN apt-get update
RUN apt-get -y install openjdk-11-jdk pip

ENV TAURUS_VERSION="1.16.34"
RUN pip install bzt==$TAURUS_VERSION

RUN bzt https://google.com -o execution.0.executor=gatling
