Is your feature request related to a problem? Please describe.

For metric data type 'Histogram', it seems that I can only get a summary data in the metric exporter.
Class DoubleHistogramPointData only have a sum, some boundaries and the count of data in each range.
It's hard for us to calculate the 95line 99line when monitoring the execution time.

Describe the solution you'd like

Would you please to provide an aggregation to collect all the recorded data points for Histogram data?
Or is there any other ways to help us to get more detailed information?
