* Refactor alpha statistics

- Refactor alpha statistics, cleaning up and simplifying no longer required calculations and scoring
- Adding new InsightEvaluator abstraction, adding C# & PY regression
  algorithms

* Optimization backtest result json converter update

* Address reviews

- Remove IAlphaHandler, move insight storage responsability to IResultHandler
  and centralizing insight collection on the QCAlgorithm.Insights to be
  reused by the framework models
- Fix portfolio turnover single day backtests and duplicate time
  sampling handling. Updating regression algorithms

* Add InsightCollection tests and minor fixes

* Adding more & improved tests

Martin Molinero b7930aff67 Performance improvements
- Using `Aggregate(lambda)` vs `Sum(lambda)` since the later is slower
due to performing an extra `Select`
- For `QCAlgorithm.Framework.OnFrameworkData()` will avoid calling
`ToArray()` on empty `Enumerables` due to its cost * the number of
calls. If the `Enumerable` is the empty instance, which is static,
will create a new empty array and return it instead.
- Replacing `SecurityIdentifier` `SecurityType` and `GetHashCode`
implementations for `Lazy` versions, that are performed just once, since
these values do not change and are used multiple times.
- For the different `DataDictionary<T>` implementations adding `this[
Symbol] get; set` since existing overload `this [string]` produces an
extra round operations `Symbol->string->Symbol` with a significant
impact.
- Adding `PortfolioTargetCollection.AddRange()` overload using an array
to avoid unnecessary convertions.

Martin Molinero 5b04cfe202 Emiting Insights based on Fills
- Classic Algorithms will emight insights based on order fills.
   - To be able to update generated insights closed time, we will not
   clone emitted insights.
   - `InsightAnalysisContext` will update `AnalysisEndTimeUtc` when the
   Insight period is closed and the period is `EndOfTimeTimeSpan`
- Adding new regression algorithm asserting on the new emitted insights
- Adding unit tests
- `LiveTradingResultHandler` will store `AlphaRunTimeStatistics`
- Making `DefaultAlphaHandler.ProcessAsynchronousEvents` virtual to
facilitate cloud changes

Michael Handschuh dd764ad8e9 Rename InsightCollection->GeneratedInsightsCollection
This type is just used as a container for generatd insights. Renaming in
preparation for a new InsightCollection to mirror the PortfolioTargetCollection
