Improve swift-ring-builder to make a set of changes easier

Registered by gholt

When adding a large amount of capacity to a cluster, it is tedious to add all the devices to the ring. Also, it's usually best to add all devices at a lower weight than is eventually desired to lessen the network and load impact on the cluster.

We'd like to improve swift-ring-builder to make this easier. An idea is to allow a list of devices be provided in a CSV file with commands to work with such lists. Such as: swift-ring-builder <builder.file> add_csv <csv.file> <weight> and swift-ring-builder <builder.file> set_weight_csv <csv.file> <weight>
