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
