Description of problem:
currently the script 
checks for oc wait pod $WEBUI_POD --for condition=Ready -n openshift-cnv --timeout=360s
where WEBUI_POD is empty
the webui have been merged with openshift-console
please remove the lines related to webui from the script 
Removed the check for the web-ui operator.
I don't see any WEBUI_POD related lines in bundle #20.
