Aleksandra Martyniuk 7b3e0ab1f2 compaction: sstables: monitor validation scrub with compaction_read_generator
Validation scrub bypasses the usual compaction machinery, though it
still needs to be tracked with compaction_progress_monitor so that
we could reach its progress from compaction task executor.

Track sstable scrub in validate mode with read monitors.
