Older examples needs to be updated for JSONFiles API changes

[pebblehut]

Describe the issue
This example has some API calls that don't work with the updated version of sasctl - changes to JSONFiles:
https://github.com/sassoftware/python-sasctl/blob/master/examples/pzmmCompleteModelExampleMLFlowSklearn.ipynb

For example, writeModelPropertiesJSON is now write_model_properties_json and has many changes in the parameters.

Other examples:
writeFileMetadataJSON
writeVarJSON

I checked other examples and it seems any of them 6 months or older are now out of date with the newer sasctl API.

To Reproduce
Run this command using latest sasctl

J.writeVarJSON(inputsDict, isInput=True, jPath=zipFolder)

and you will get things like

AttributeError: 'JSONFiles' object has no attribute 'writeVarJSON'. Did you mean: 'write_var_json'?

Version
The SHA is 729e72c

Hello,
I was going through the notebook mentioned above and I noticed that more things have changed since sasctl v1.8.2:

• writeVarJSON() has been renamed write_var_json();
• writeModelPropertiesJSON() has been renamed write_model_properties_json();
• writeFileMetadataJSON() has been renamed write_file_metadata_json();

also for each of those methods some parameters have a different name and use snake-case instead of camel-case.
Moreover, the parameters of writeModelPropertiesJSON() used in the notebook do not all match the ones in write_model_properties_json() :

• targetEvent:int and numTargetCategories:int do not exists anymore, I think they have been substituted with target_values:list
• eventProbVar i believe has also been removed because it is handled in the code directly
• modelType is now model_algorithm
• modelPredictors has been removed

I will update if I find more.
