    @rhtyd On the contrary, I think you adding metrics as pluggable API is a 
good idea. However, to seriously make the feature pluggable the UI component 
should also load based on a plugin based flag.
    
    For example (I am not sure if the current design makes this possible), the 
plugin should return a flag in the listCapabilities API which tells the UI that 
metrics is enabled. If this flag is present, the metrics button should appear, 
else not.

> 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.
