Florian Hines 00dbad0825 Add optional locking to swift-ring-builder ... If invoked as 'swift-ring-builder-safe' the directory containing the builder file provided will be locked (via lock_parent_directory()). This provides a small safe guard against multiple instances of the swift-ring-builder (or other utilities that observe this lock) from attempting to write to or read the builder/ring files while operations are in progress. This is particularly useful in environments where ring management has been automated (via Chef or custom solutions) but the operator still occasionally needs to manually interact with the ring.
