```
and so on. few other tests would be failing with same symptoms, because directory missing and non-writable by regular user. 

**Release note**:
```release-note
NONE
```

Currently if developer tries to run integration tests locally,
it would be failing due to missing /var/run/kubernetes inside
cross container image. As tests are run by non-privileged
user, this directory must be pre-created and made user
writable at the time cross build/test container created.
