CI: parsing error while installing cliff

[Aakarsh]

Can be noticed in at least the CI jobs that use prep-internal-rhel.sh.

Ex:

periodic-{pike/queens}-rdo_trunk-featureset020-1ctlr_1comp_64gb
All of the PerfCI jobs.

Following error can be seen:

The error occurs despite updating setuptools to the latest version

Looks like a global issue
https://bugs.launchpad.net/python-cliff/+bug/1597846

[wes hayutin (weshayutin)]

Root cause in https://rhos-dev-jenkins.rhev-ci-vms.eng.rdu2.redhat.com is old jenkins slaves.

Fails on:
[root@dhcp-12-53-28 ~]# cat /etc/redhat-release
Fedora release 22 (Twenty Two)
[root@dhcp-12-53-28 ~]#

Works on:
[root@dhcp-12-53-28 ~]# cat /etc/redhat-release
Fedora release 22 (Twenty Two)
[root@dhcp-12-53-28 ~]#

Closing the bug, please upgrade your jenkins slaves to a more recent version of fedora or centos.

Thanks
