Cleaner solution is to just replace helm template on line 33(34) and add helm_timeout_option to the parameters - the rest looks the same

[jfilipcz]

Definitely, I've replaced helm template with helm install and remove oc apply part as it's no longer needed

[oybed]

ha - no no - we need to support the template action. Sorry, should have been more clear ... replace helm template with helm {{ helm.command }}

[oybed]

Also, to be consistent with other parts of the openshift-applier inventory, use the word action instead of command
