Description of problem:

If you look at oVirt 4.6,4.5 and 4.4 release jobs [1][2][3]
you can notice that a very high number of tests are failing.
This is due to the docker rate limiting[4]:
"""
May 24 13:24:12.758: INFO: At 2021-05-24 13:21:45 +0000 UTC - event for simplev1-r6rfq:

Failed: Failed to pull image "docker.io/busybox": rpc error: code = Unknown desc = Error reading manifest latest in docker.io/library/busybox: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit
"""

This problem got fixed for other providers, need to check if we need to purchase a docker account or if there is a different way to workaround this.
