[go-experimental] Add model constructors to initialize non-container vars with defaults (#5175)

* [go-experimental] Add model constructors to initialize non-container vars with defaults

* Add docstring and extend model_doc to include the constructor

* Make variable names in constructor follow Go naming guidelines

* Provide 2 different constructurs as suggested + couple fixes to generate constructors right under all circumstances

* Fix defaults for enums

* Properly escape vars that have reserved names
