      * Previously, your cluster could experience a timeout when pulling images if you use Zscaler and scan all transfers. This was due to a hard-coded timeout value for image pulls. This fix increased the pull progress timeout of CRI-O to 30 seconds. As a result, your cluster should not experience timeout under these circumstances.

      Description of problem:

      After introducing `pull-progress-timeout` in https://issues.redhat.com/browse/OCPBUGS-33075, customer experiences timeout when pulling images because they use zscaler and scans all tranfers. This results on a 10-15 seconds minimum to send a bit. When the client disconnects - in this particular case, crio- the scan is abort. This leads to a loop and the customer is unable to pull image at all. This blocks customer updating to 4.16.37 + since no Red Hat image can be pulled.
