Jhonathan Abreu 2ddf40b8e9 PEP8 style algorithm API (#7909)
* feat: support snake-case style Python QCAlgorithm implementations

* feat: add unit tests and minor fixes

* feat: implement new BasePythonWrapper class for python wrappers.

Used to cache methods and contains invoke functionality

* feat: keep overriden methods in Algorithm Python Wrapper

* feat: add unit tests for custom models algorithms with PEP8 style

* Bump pythonnet version to 2.0.30

* fix bugs and address peer review

* Address peer review

* Minor revert

* feat: StubsIgnoreAttribute for ignoring members or classes by the stubs generator

* Minor fixes

* Minor fix

* Minor fix

* Bump pythonnet version to 2.0.31

* Added Greeks.Lambda_ alias of Lambda for python compatibility.

Remove unused method

Martin Molinero 8e71e48c07 PythonSlice
- AlgorithmPythonWrapper will directly call base OnFrameworkData()
  implementation skipping going through python and it's overhead
- Small performance improvement for adding Tick data points into a Ticks
  collection
- For python always wrap slice with PythonSlice, so that slice.Get()
  works even when no custom data is present, adding test.

Martin Molinero fa122fa809 Add missing PyObject.Dispose calls
- Adding _some_ of the missing PyObject.Dispose calls. In the cases
where C# is calling the Python side.
   - Note that Python calls to C# code is correctly handling the
   disposure of resources.

Martin Molinero cfa08a11fb Address reviews
- Removing `using QCAlgorithmFramework = QuantConnect.Algorithm.QCAlgorithm`
- Removing `QCAlgorithmFrameworkBridge`
- Removing `IsFrameworkAlgorithm`
- Making `EmitInsightBasedOnFill` private. Adding new
`IOrderEventProvider` exposing an `event` to which `QCAlgorithm` will
subscribe.
- `AccountType.Cash` algorithms will be allowed to manually trade and
emight insights manually or with alpha model.

Martin Molinero 32ac3146b4 Merge Framework and Classic Algorithms
- Merging Framework and Bridge algorithms into classic QCAlgorithm
class.
- Removing Framework project, VS17 and VS15
