Description

In Ozone (SCM/KSM) web ui we have additional visualization if rpc.metrics.percentiles.intervals are enabled.

But according to the feedbacks it's a little bit confusing what is it exactly.

I would like to improve it and clarify how does it work.

1. I will to add a footnote about these are not rolling windows but just display of the last fixed window.

2. I would like to rearrange the layout. As the different windows are independent, I would show them in different lines and group by the intervals and not by RpcQueueTime/RpcProcessingTime.
