We need to make sure the example snippets that we place on READMEs are valid

The following snippets are no longer valid after the refactoring of the modules

Public LB example

╷
│ Error: Missing required argument
│ 
│   on main.tf line 1, in module "lbe":
│    1: module "lbe" {
│ 
│ The argument "backend_name" is required, but no definition was found.

In VMSS usage example the following variable are no longer valid

vm_image_configuration = {
    img_version = "10.2.4"
  }
