fix(ci): waiting for a pod using k8s wait command

Previously we were looking for the phase and then checking if the pod is Running. Instead of that, we can use oc wait command.

Timeout of 30 seconds is really less it has to be more than that because of the NFS file system storing images. The image-pulling time can be longer.
