optimize metric aggregations order by

[skjindal93]

Description

Keeping this as a draft PR, since none of the use cases need this optimization yet. The optimization comes into play when there is a filter on an attribute in EDS and order by on QS aggregations

Pushes the metric aggregation order by down as a selection, so that only required data is fetched for paginating in memory, instead of fetching all the data for pagination

Testing

Tested end to end
