change replication_type to ReplicaPlacement, hopefully cleaner code works for 9 possible ReplicaPlacement xyz x : number of copies on other data centers y : number of copies on other racks z : number of copies on current rack x y z each can be 0,1,2 Minor: weed server "-mdir" default to "-dir" if empty
