> For diverged quasi-closed stuck containers, HDDS-12483 keeps two copies of
> each origin. This change makes the replica counts configurable, so the origin
> with the highest BCSID can receive more copies than the others for better
> fault tolerance.The best origin is defined as the one with the highest BCSID
> among healthy replicas. If the highest BCSID replica is unhealthy, we fall
> back to the next highest healthy one. If multiple origins tie for the highest
> healthy BCSID, all of them are treated as best. Two new reconfigurable config
> keys are introduced:
> * hdds.scm.replication.quasi.closed.stuck.best.origin.copies (default: 3)
> * hdds.scm.replication.quasi.closed.stuck.other.origin.copies (default: 2)
> With the defaults, the best origin gets 3 copies and all other origins get 2.
