Managerclient: display new restore flags

[Michal-Leszczynski]

This PR makes it so that the new restore flags introduced in SM 3.4 are displayed in the sctool restore --dry-run output.
Example:

miles@fedora:~/scylla-manager$ ./sctool.dev restore -L s3:restoretest-my -T sm_20241023115845UTC --rate-limit 'dc1:0,dc2:1' -c myc --dry-run --restore-tables --parallel 3 --transfers 100
NOTICE: dry run mode, restore is not scheduled

Restored tables:
  - system_traces: 0 (5 tables)
  - system_distributed: 0 (1 table)
  - mks: 5.104k (1 table)

Disk size: ~5.104k
