Add generators for creating basic operations and forms

[Misha7776]

Would be great to have some sort of generator that will create operations and forms based on a base template.
This could look like this:
readymade generate scaffold Posts - generates operations and forms for Post model (additionally we can arguments that will be validated in the form)
readymade generate Posts::Actions::Notify - will create a empty namespaces class with call method
readymade generate Posts::Operations::Create - will create a basic operation
readymade generate Post::Foms::Create permitted:[] required:[] - will create a form class
What do you think @OrestF ?

@Misha7776 sounds good
but let's keep it simple
I would make generators for declared classes without scaffolding.
Do you have an idea how to implement this?
