Need to force ANA reporting to True also in gRPC

[gbregman]

Long ago we changed the CLI to always use True for ANA reporting when creating a subsystem. But, a user bypassing the CLI and using gRPC directly can still pass False and create a subsystem without ANA. This might cause issues as we rely on the ANA information in different places. We need to force ANA reporting to True in gRPC as well.

I was wrong. We already check in gRPC and fail the create subsystem command in case "enable_ha" is false. But, we still have some leftovers from the times we could have false. So we need to clean them up.
