jonathanwu906 77caa034e3 Add Python version of IndicatorVolatilityModelAlgorithm (#9580)
Port the C# regression algorithm demonstrating IndicatorVolatilityModel
usage, including how to reset and warm up the indicator on splits and
dividends to avoid volatility jumps from price discontinuities, and
enable the Python variant in the regression test suite.

Closes #6375

* Default daily precise end times

- Enable by default daily precise end times. Updating stats
- Minor fix for algorithm manager consolidator updates, adding new regression test
  asserting behavior and updating others
- Minor fix for SubscriptionData creator avoid round down on warmup if
  not appropiate
- Adjust consolidators to emit on daily strict end times if requested
  daily resolution and setting enabled
- Updating regression algorithms

* Skip daily data on extended market hours

* Some cleanup and self review

* Revert unrequired change

Ricardo Andrés Marino Rojas a2b420cb0a Fix warnings part 8 (#8113)
* Fix CA1819 and CA1002 warnings

Changed the type of Languages statistic in regression tests from
Language[] to List<Language>. By doing that, the warning CA1819 was
removed but then the warning CA1002 was raised. However, this warning
was expected to be excluded from QuantConnect.Algorithm.CSharp.

* Improve implementation

* Simplify code

* Fix bugs
