CLOUDSTACK-9783: Improve metrics view performance
This improves the metrics view feature by improving the rendering performance
of metrics view tables, by reimplementing the logic at the backend and data
served via APIs. In large environments, the older implementation would
make several API calls that increases both network and database load.
List of APIs introduced for improving the performance:
listClustersMetrics
listHostsMetrics
listInfrastructure
listStoragePoolsMetrics
listVMsMetrics
listVolumesMetrics
listZonesMetrics

>
> Metrics view is a pure frontend feature, where several API calls are made to
> generate the metrics view tabular data. In very large environments, rendering
> of these tables can take a lot of time, especially when there is high
> latency. The improvement task is to reimplement this feature by moving the
> logic to backend so metrics calculations happen at the backend and final
> result can be served by a single API request.
