H20 Reuse one model table

Goal: Select a member table deliberately.

Prerequisites: H19.

The table argument selects one table from a successful model result.

training_step(
  "H20",
  {
    selected_product <- dr_product(
      "portfolio.policies",
      model_run,
      table = "policies"
    )
    selected_run <- dr_run(selected_product, write = FALSE)
    selected_rows <- dr_collect(selected_run)
    print(selected_rows)
    stopifnot(nrow(selected_rows) == 6L)
  },
  needs = c("H19")
)

Expected result: Six policies with customer and broker IDs.

Task: Have we lost the dm model?
