as backend APIs, will post a PR this/next week. Thanks.

> The Metrics view for each type of entity basically fires APIs and calculates
> required values on the client end. For e.g. to display memory usage etc at
> the zone level, it will fetch all zones. For each zone it will fetch
> pods->cluster->host->VMs
> For a very large Cloudstack installation this will have a major impact on the
> performance.
> Ideally, there should be an API which calculates all this in the backend and
> the UI should simply show the values. However, for the time, introduce a
> global setting called enable.metrics which will be set to false. This will
> cause the metrics button not to be shown on any of the pages.
> If the Admin changes this to true, then the button will be visible and
> Metrics functionality will work as usual.
