* CPU to Memory weight based algorithm to order cluster
host.capacityType.to.order.clusters config will support new algorithm: COMBINED
which will work with host.capacityType.to.order.clusters.cputomemoryweight and capacity will be
computed based on CPU and memory both and using weight factor
* minor changes
* add unit tests
* update desc and add validation
* handle copilot review comments
* add log indicating chosen capacityType for ordering
