[feat] Hidden models and model properties

[germanamz]

Background
Currently all models and their keys get generated and are readable from apis.

Task
Prisma-rest should provide a way to hide models or properties based of comments in the prisma schema using prisma's 3 slash comments

Example of a hidden property

model SomeModel {
  /// @crud.hidden
  property PropType
}

Example of a hidden model

/// @crud.hidden
model SomeModel {
  property PropType
}

CRUD:

• If a model is hidden should not generate models service
• If a property is hidden it should be accessible from crud

APIs:

• If a model is hidden should not generate models api
• If a property is hidden it should be accessible from apis
