https://github.com/rook/rook/issues/3106

The orchestrator manager modules (rook and deepsea) both assert that service types fall into a fixed set which excludes the `iscsi` type. The dashboard requests this type, and fails when it subsequently attempts to iterate over NoneType that results from the assertion failure.

I think the orchestrator modules should be returning something like an empty set, but presumably dashboard and orchestrator should coordinate on this change.
