Benny Halevy 57cc5f6ae1 sstable_directory: use a external load_semaphore

Although each sstable_directory limits concurrency using
max_concurrent_for_each, there could be a large number
of calls to do_for_each_sstable running in parallel
(e.g per keyspace X per table in the distributed_loader).

To cap parallelism across sstable_directory instances and
concurrent calls to do_for_each_sstable, start a sharded<semaphore>
and pass a shared semaphore& to the sstable_directory:s.
