data source to validate image structure about terraform-provider-oci

[imjasonh]

We (edit: don't) need separate data sources for validating images and indexes.

image is a misnomer though, maybe digest instead?

data "oci_ref" "alpine" {
  ref = "alpine"
}

data "oci_validate" "validate" {
  image = oci_ref.alpine.image_ref
  test {
    rule = keys(oci_ref.alpine.manifests) = ["linux/amd64", "linux/arm64"]
  }
  # TODO: test index annotations and SBOM
}

data "oci_validate" "validate" {
  # test each platform
  for_each = keys(oci_ref.alpine.manifests)
  image = each.value.image_ref

  test {
    path     = "/etc/passwd"
    contains = "nobody"
  }
  # TODO: test image annotations and SBOM
}
