[virt] Adding CNV docs to OKD

[ousleyp]

• This PR adds the CNV docs to the openshift-origin distro and changes the top-level ToC label to "Virtualization" to avoid "OpenShift" appearing in OKD (or vice versa). Similarly, the "Installing OpenShift Virtualization" ToC label is now "Installing" (which matches OpenShift).

• There is now an ifdef statement in the virt-document-attributes file so that {VirtProductName} renders as "OKD Virtualization" in the openshift-origin distro.

• Most changes originate from this PR by @sandrobonazzola: OKD: Add Virtualization documentation #36612

• CP to enterprise-4.9

• QE approved; needs peer review

• Note: Netlify does not do an openshift-origin preview build. You can view the changes pertaining to openshift-enterprise here. I uploaded a preview build for the OKD changes, which you can view here: http://file.rdu.redhat.com/pousley/101221/okd-virt-docs/welcome/
