insights: refactor- update insight view resolver to preload series data for the 1 case it didn't already
Created by: chwarwick
Previously the timeseries was loaded in the InsightViewResolver for JustInTime and Capture Group recorded series. Move the loading of the standard search timeseries data into InsightViewResolver for consistency.
Removed unused arguments to dataPoints field.
Marked legacy insights query as deprecated and a todo to remove a resolver that should be removed when insights is removed.
