Glauber Costa f49e965d78 repair: rework repair code so we can limit parallelism ...

The repair code as it is right now is a bit convoluted: it resorts to detached
continuations + do_for_each when calling sync_ranges, and deals with the
problem of excessive parallelism by employing a semaphore inside that range.

Still, even by doing that, we still generate a great number of
checksum requests because the ranges themselves are processed in parallel.

It would be better to have a single-semaphore to limit the overall parallelism
for all requests.
