Need to be able to specify an older version of OCP when installing on ARO

Some products, such as Cloud Paks from IBM, that run on top of OpenShift are not necessarily in syched with the latest version of OpenShift. They may be 1 minor version behind because they cannot test the new OCP version ahead of time before it gets released.

Having said that, this introduces a major problem when a customer wants to use a Cloud Pak product on ARO. The ability to specify an older version is a major need in this use case, or this will cause a customer to drop ARO as an option since ARO is not the only way that the Cloud Pak products can be deployed. Microsoft may be losing revenues if you don't support this scenario.
