             Summary: EC: Change ContainerReplicaPendingOps to store deadline rather than scheduled time
                 Key: HDDS-7928
                 URL: https://issues.apache.org/jira/browse/HDDS-7928
             Project: Apache Ozone
          Issue Type: Sub-task
          Components: SCM
            Reporter: Stephen O'Donnell
            Assignee: Stephen O'Donnell


In order to facilitate a "Move Manager" for the balancer, we need to schedule pending ops on the datanodes with different deadlines.

For example, as replica scheduled due to replication would have a timeout of 10 minutes.

However the balancer schedules large batches of work each hour, so replicas scheduled by the balancer probably need a timeout of 60 minutes.

To facilitate this, we need to change containerReplicaPending ops to store the deadline rather than the scheduled time. This also fixes another issue, in that the ContainerReplicaPendingOps "expiry thread" had its own setting for the timeout for all pending ops, and it is not related to the replication manager settings.

As part of this change, some APIs into RM has been changed a little to allow the move manager to schedule replication commands via RM, so that logic is consolidated in a single place. A later PR that adds the MoveManager will use these APIs.
