Reopening this issue. When trying to run terraform apply, I get the following:

│ Error: Unsupported argument
│ 
│   on main.tf line 29, in resource "rancher2_cluster" "cluster":
│   29:     outbound_type              = var.outbound_type
│ 
│ An argument named "outbound_type" is not expected here. Did you mean "outboung_type"?

Looking at the code, the typo outboung_type is there. FWIW, this change works, but the typo needs to be fixed to have outbound_type before QA will close this issue.
