Reference VMWare docs from Production Checklist

Chris Casano (chriscasano) commented:

Alex Entin did an awesome job building out best practices around running CockroachDB on VMWare. We should highlight a reference to this doc: https://core.vmware.com/resource/cockroachdb-vmware-cloud-foundation#overview from our docs. It probably makes sense to have a call out in our Production Checklist area that can link to these docs host on VMWare. If you search for VMWare in our docs site, unfortunately no results are returned.
