    I'm working on improving the metrics view feature by implementing the logic 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.
