Refactoring the body using dynamic type

[magodo]

As hashicorp/terraform-plugin-framework#147 is resolved, the terraform-plugin-framework now has support for dynamic type. We shall consider using dynamic types instead of a plain string (JSON) for better UX, includes:

• Easier to author. You can now use native HCL to define the body. Also you reference the attribute of the output natively
• Native supports of ignore_changes
• Customizable decoration on the fields in body, including:
  • Mark a field as sensitive by using sensitive
  • Mark an array order insensitive by using toset
  • etc.
