Do pip install quiet.

This will still keep it quiet, but throw some information when something goes wrong - and it's look nicer 😄

@qiliRedHat PTAL - I don't want to merge this without your check first.

@skordas Thanks. Are you using reliabilty-v2 or play with it? I'm just curious why you had the idea to change the code here. Let me do a test to make sure it works well before I approve.

Hi @qiliRedHat
This script is used in prow: https://github.com/openshift/release/blob/master/ci-operator/step-registry/openshift/svt/reliability-v2/openshift-svt-reliability-v2-commands.sh
in openshift-svt-master__reliability-v2-aws-4.18-nightly-x86 tests.

I was running this test and was failing without info why...
pip3 install -r requirements.txt > /dev/null 2>&1 is sending everything to /dev/null
and -p flag it's make it nicer 😄
