confluent_transit_gateway_attachment resource re-creates attachment when routes changes

[ernesto-hrp]

Please make it so when updating the routes list of the confluent_transit_gateway_attachment resource the attachment is not recreated. Every time I have to update this I need to file a support ticket, so I trust you guys can update the code here to not make it recreate it.

resource "confluent_transit_gateway_attachment" "this" {
  display_name = "transit-gateway-attachment"
  aws {
    ram_resource_share_arn = <share_arn>
    transit_gateway_id     = <gateway_id>
    routes = [...] # <---- CHANGING THIS RECREATES THE ATTACHMENT.
  }
  environment {
    id = enviornment
  }
  network {
    id = network_id
  }
}

Thank you for filing this request.

Currently, the backend API for transit gateway attachment does not support updating the spec.cloud.routes attributes.
We will need to update the PATCH API for changing the routes, before we can support updating the routes in the Terraform provider.
