----------------------------------------
Superseded by HDDS-15412 / PR #10693.
Per-volume push replication thread pools in VolumeReplicationThreadPools
replace the HddsVolume outbound counter approach. PR #10128 is closed; no
further work planned.

> Introduce hdds.datanode.replication.volume.outbound.limit to restrict
> concurrent replication reads per physical disk. Add an
> activeOutboundReplications
> atomic counter to HddsVolume to track current disk-level load. Update
> OnDemandContainerReplicationSource and EC source providers to
> increment/decrement
> this counter during container streaming. This provides the infrastructure
> for disk-level fairness.
