Parallel and Multi-Library Recall Scheduling

For large restore operations, Deep Archive should provide more explicit control and visibility over recall scheduling.

For example, when retrieving 256 files of 100 MiB each, the documentation describes a recall workload involving multiple tapes and tape drives. However, from an operational perspective, it would be useful to expose how the workload is internally partitioned into recall tasks and how those tasks are assigned to libraries and drives.

In a multi-library configuration, Deep Archive could dynamically distribute independent recall tasks across the available libraries, based on tape location, library workload, drive availability, and expected seek/mount overhead.

The objective would be to maximize aggregate recall throughput while minimizing unnecessary tape mounts and library contention.

A useful enhancement would be to expose this scheduling information through dacli task list, including the library, tape drive, and estimated/actual progress associated with each recall task.
