[SL-1629] Enable support for predicate pushdown for queries involving time range adjustments (e.g., offsets, cumulative)

[tlento]

For any case where we have applied an appropriate granularity adjustments, we should enable predicate pushdown of time filters for metrics requiring time windows.

Initially this can be done without detection by relying on the start_time/end_time construct for testing, and as such it can be handled in parallel with #1013
