Can we switch over to using this in our CI?

[Sharpz7]

Are we able to include the actual make command for the e2e tests in this work to??

i.e

tests-e2e-python: python
	docker run -v${PWD}/client/python:/code --workdir /code -e ARMADA_SERVER=server -e ARMADA_PORT=50051 --entrypoint python3 --network=kind armada-python-client-builder:latest -m pytest -v -s /code/tests/integration/test_no_auth.py

# To run integration tests with jobservice and such, we can run this command
# For now, let's just have it in rare cases that people need to test.
# You must have an existing cluster working to run this command.
.ONESHELL:
tests-e2e-airflow: airflow-operator build-docker-jobservice
	$(GO_CMD) go run cmd/armadactl/main.go create queue queue-a || true
	docker rm -f jobservice || true
	docker run -d --name jobservice --network=kind --mount 'type=bind,src=${PWD}/e2e,dst=/e2e' armada-jobservice run --config /e2e/setup/jobservice.yaml
	docker run -v ${PWD}/e2e:/e2e -v ${PWD}/third_party/airflow:/code --workdir /code -e ARMADA_SERVER=server -e ARMADA_PORT=50051 -e JOB_SERVICE_HOST=jobservice -e JOB_SERVICE_PORT=60003 --entrypoint python3 --network=kind armada-airflow-operator-builder:latest -m pytest -v -s /code/tests/integration/test_airflow_operator_logic.py
	docker rm -f jobservice
	```

Since @nitishchauhan0022 is working on the mage refactor he wanted to get this one merged. I think that is fine as we will switch over to using mage in that PR.
