This patch implements repair's "primaryRange" and "ranges" options: Without these options, a repair defaults to repair all the ranges for which this nodes holds a replica (each range is repaired by contacting the other replicas of this range). If the "primaryRange" option is passed, instead of repairing all ranges, only the "primary ranges" of this node is repaired - for each range, only one node has this range as its "primary range". The intention is that a user can start a "primaryRange" repair on all nodes, and the result would be that each range will only be repaired once. If the "ranges" option is passed, it can explicitly list a list of ranges to repair, overriding the automatic determination of ranges explained above. Fixes #212.
