ERROR: openshift 0.10.0 has requirement kubernetes~=10.0, but you'll have kubernetes 9.0.0 which is incompatible.
There seems to be some mishmash between required versions of kubernetes and openshift. Requirement installation (`pip3 install -r requirements.txt`) prints following error (even  though finish with error code `0`):
```
ERROR: openshift 0.10.0 has requirement kubernetes~=10.0, but you'll have kubernetes 9.0.0 which is incompatible.
```
And then `run-ci ...` command fails like [this](https://ocs4-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/job/qe-destroy-ocs-cluster/1232/console):
```
