Portforward 0.4.3 hanging forever with pytest

[alaeddine-13]

• portforward version: 0.4.3
• Python version: Python 3.8.8
• Operating System: Ubunutu 18.0.4

Description

It looks like portforward when used within a pytest environment, it will hang forever. In Jina's CI tests, we use portforward to test deployed services. However, since the latest 0.4.3, the CI will hang forever right when portforward is called. Therefore, we had to limit the portforward version to 0.4.2

What I Did

in a pytest script, do portforwarding to any pod:

with portforward.forward(
    namespace, pod_name, port, port, config_path
):

this will hang forever
