Asias He 47345078ec repair: Repair on all shards ...

Currently, shard zero is the coordinator of the repair. All the work of
checksuming of the local node and sending of the repair checksum rpc
verb is done on shard zero only. This causes other shards being
underutilized.

With this patch, we split the ranges need to be repaired into at least
smp::count ranges, so sizeof(ranges) / smp::count will be assigned to
each shard. For exmaple, we have 8 shards and 256 ragnes, each shard
will repair 32 ranges. Each shard will repair the 32 ranges
sequencially.  There will be at most 8 (smp::count) ranges of repair in
parallel.
