Update existing metric definitions:

• All existing traditional subscriptions' metrics are gauges.
• All existing payg subscriptions' metrics are counters.

property name: type
values: gauge || counter

For example:
... in rhel for x86
metrics:
  - id: Sockets
    type: gauge
    ...

... in ROSA
  - id: Cores
    type: counter
    ...

There is no change in existing behavior based on this today. 

Testing, look at the product configuration and ensure that the gauge is specified on all metrics in the variants. Start considering the updates needed for IQE tests when this value starts to be used directly.
