Jenkins PEP8 job failing with "RuntimeError: Unable to import module nova.openstack.common.sslutils"

[Matthew Gilliard]

This prevents Jenkins from being able to generate the nova.conf.sample, which causes the Nova pep8 job to fail.

The main problem here is: Error importing module nova.openstack.common.sslutils: duplicate option: ca_file

That's because of https://review.openstack.org/#/c/71997/ merged to oslo.messaging - and now released

Author changed opts not only in oslo.messaging files, but also in openstack.compute one - sslutils - and we've got duplicate option error with openstack.common.sslutils in nova.

As I discussed that with Doug Hellmann, on #openstack-dev some days ago, he proposed to merge the same fix to oslo-incubator and then update all other projects using oslo.messaging.

Here is the fix: https://review.openstack.org/#/c/76300/

And the same error in Climate project: https://bugs.launchpad.net/climate/+bug/1284749 - oslo.messaging was 'master' that time, now it's released
