[RFE] Verify if container registry is up & running prior running a workload with builds

[rsevilla87]

Is your feature request related to a problem? Please describe.

It would be a nice feature to provide kube-burner the ability to verify if the internal container registry is up and running in the cluster under test.

Describe the solution you'd like

This feature should only affect the OCP wrapper, since it's mainly OpenShift related, just a simple check to query the image-registry cluster operator object to determine if it's ready or not should be enough, I wouldn't verify if it's working well or not for the sake of complexity.

$ oc get co image-registry -o yaml
apiVersion: config.openshift.io/v1
kind: ClusterOperator

Additional context
In some platforms, like bare metal for example, the internal registry is not configured by default, and running a cluster-density workload would fail without it. Having the ability of reporting if the container registry is up & running prior running the workload would provide a useful information to the user.

@akrzos : When this RFE is part of a new kube-burner release 1, we should update the version installed by jetlag (currently v1.3). I will monitor this in any case, this is just fyi.
