Review Comment:
For backward compatibility, don't we need to multiply the limit in
calculateBrokerHostUsage?
```
public void calculateBrokerHostUsage() {
...
double totalCpuLimit = getTotalCpuLimit(isCGroupsEnabled);
if (isCGroupsEnabled && metrics != null && getCpuUsageMethod !=
null) {
// cgroup cpuUsage is already scaled, [0.0, 1.0]
usage.setCpu(new ResourceUsage(cpuUsage * totalCpuLimit,
totalCpuLimit));
} else {
usage.setCpu(new ResourceUsage(cpuUsage, totalCpuLimit));
}
```
