> CASSANDRA-2324 introduces the ability to do a repair only on a given range. This ticket
proposes to add a nodetool repairPrimaryRange to trigger the repair of only the primary range
of a node. This allows to repair a full cluster without any work duplication (or at least
make it much simpler). This also introdude a global_repair command to clustertool to trigger
the primary range repair on each node of the cluster one after another (we could do all in
parallel, but that's probably not nice on the cluster).
