Upgrade horizontal scaling information (Keda)

[Richard87]

Example response:

Note: Limitations in Keda status/hpa status fields causes resource types to match on the first type (so the code below will be invalid for duplicate cpu and memory triggers (only the first of each type is correct, the other is duplicated)

The deprecated "annotation" is not propagated to swagger.json (if that was the intention), nor does it flag it as deprecated to the linters.
