[WIP] [PoC] Remove Time Series Specific Logic from V1 Engine

[ankitsultana]

While thinking about optimizing TimeSeriesAggregationOperator, one of the approaches I ended up trying was to remove dependence from time series specific code from the V1 Engine. Instead, this PR relies on a new Transform and an Aggregation function that can be run using the existing GroupByOperator and AggregationOperator.

This is a WIP.
