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.
