Proposed title of this feature request

CoreOS template definition in the install-config.yaml

What is the nature and description of the request?
My customer would like to be able to do the following:

We would like to be able to point to an existing CoreOS template in the install-config.yaml during installation, and skip the current method of the installer to upload the template each time you install a cluster.

I think this is a good suggestion, although we would need to be clear any management of templates is the customers issue, but to allow in the install-config.yaml an option to point at a template would be good.

3. Why does the customer need this? (List the business requirements here)

The reason for this is a multitude:

• Remote work uploading a new template via VPN is a hassle
• with multiple cluster having the same template multiple times is a waste.
• save time during installation testing
• easier management of templates at a central place for vsphere management

4. List any affected packages or components.
