Bug Description

For some commands, openstack client dumps details of HTTP requests and responses on the console. It dumps such details on stderr. This debug output breaks automation scripts that expect standard JSON.
For example, the command below - see attachment for the output

openstack --insecure server list --name ivt-jenkins --format json > openstack_server.stdout.log 2>openstack_server.stderr.log

(Sorry, cannot attach stdout and stderr as separate files, this issue tracker accepts only one attachment.)
However, this command does not have such problem and reports only the requested info:

openstack --insecure network list --name ivt-net --format json

This seems to be cause by python-novaclient==9.0.0, it disappear if I downgrade that to 8.0.0.

Strangely also volume commands seem to be affected.

By 'volume commands' do you mean OSC volume commands? Because that would be cinderclient and point to a possible shared common library problem.

"volume show" does a "server show" internally in order to display attachments.

Looking at the diff between 8.0.0 and 9.0.0 it seems that the change in I60c8a023cff92f8b6f37a4a14b6193c3efaa19a8 to novaclient/v2/client.py is the culprit, adding logger.addHandler(logging.StreamHandler()). Not sure about a proper fix, though.

    Revert "client.logger.warning wrongly used in migrations"

    This is a partial revert of the previous patch. The inline setup of
    the logger ends up causing issues when this is consumed by other
    libraries that want control over the logger.

    Closes-Bug: #1697452

    This reverts commit 9a272014167390217351dd5a60f50f518f4ae600.
