DAOS-17358 test: add int_rebuild_dkeys_stop_failing()

[kccain]

Using the interactive rebuild feature, stop a repeatedly-failing rebuild (triggered by a rank targets exclusion). Use command dmg system stop --force while the failing rebuild is in its Fail_reclaim stage. New common test functions are added to support waiting for the pool rebuild state rs_version to be below a given version.
