Specify installer image for the `talos_machine_configuration_apply`

[mircea-pavel-anton]

Given that the current workflow requires users to specify a custom installer image, I think it would be better to have a dedicated field in the talos_machine_configuration_apply to specify an installer image, that way it can also be taken into account during upgrades, since, as far as I can tell from some minimal testing, there is no clear way to specify an installer image for upgrades so that system extensions are taken into account.

TF provider doesn't support upgrades at the moment.

You can set up the config_patches argument in talos_machine_configuration_apply like this:

resource "talos_machine_configuration_apply" "example" {
...
  config_patches = [
    yamlencode({
      machine = {
        install = {
          image = "factory.talos.dev/installer/<image_id>:v1.7.4"
        }
      }
    })
  ]
}

Remember: custom installer image is a key of configuration YAML file used by Talos. So, you can use config_patches argument to solve it.
