* 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

* Fix index option data timezone
- Fix index option data timezone which was 1 hour late than expected
* Update existing index option tests
- Update existing index option tests.
- Disable index option daily resolution support
* Fixes Regression Algorithm Testing No Warm Up Requirement
* Removes Volatility Model Warm Up Requirement
If the volatiliy model is not ready, we will use the Brenner and Subrahmanyam (1988) approximation (BS88).
Lean will not set the volatility model if the user doesn't, since the BS88 can handle the null model case.
* Using IV to calculate Greeks, and remove single-step stochastic approximation
* Correct calculation for theta, vega, rho
* Add calculation from Black Calculator and peer review
* Address peer review and added unit test
* Update some tests and correct vega/eho
* Fix Unit Test and Improve Comments
Fixes `IndexOptionCallITMGreeksExpiryRegressionAlgorithm` since `Vega` was really non-zero.
* Fix regression test and add IV calculation
* refactor and bug fixing on peer review
* refactor and bug fixing on peer review
* for rerun test
* add warning on IV estimation not coveraged and edit speed unit test to not exceed 2s per 1000 iteration
* update logging
* update logging and description
* Add default option pricing models and unit tests
* address review
* Added Fed interest rate as risk-free rate with unit tests and set as default for option greeks calculation, added regression algorithms, addressed peer review
* refactor structure of interest rate
* Skip Saturday and Sunday
* regression test fix
* peer review
* Fixes Interest Rate Provider Logic
* Minor tweaks
* Fix start date
* Minor test tweak
* Update interest rates
* Fix unit tests
