    Description

      Currently when label-queue mappings are not available, there are few assumptions taken in UI and in metrics.

      In above case where labels are enabled and available in cluster but without any queue mappings, UI displays queues under labels. This is not correct.
      Currently labels enabled check and availability of labels are considered to render scheduler UI. Henceforth we also need to check whether

      • queue-mappings are available
      • nodes are mapped with labels with proper exclusivity flags on

      This ticket also will try to see the default configurations in queue when labels are not mapped.
