CapacityScaler: A multiplier applied to the group's maximum servicing capacity (either UTILIZATION or RATE). Default value is 1, which means the group will serve up to 100% of its configured CPU or RPS (depending on balancingMode). A setting of 0 means the group is completely drained, offering 0% of its available CPU or RPS. Valid range is [0.0,1.0].
This cannot be used for internal load balancing.
