Support new OpenStack initialization resource for RHOSO install

[abays]

We have a new upcoming way to install and deploy the OSP operators. OLM will only install one CRD for OSP, which is an initialization resource. A CR must be created for that CRD, which then, when created, causes all the remaining OSP CRDs to be installed and also deploys their respective operators.
