Adds a repair command that reads shard ranges from the container DB, identifies overlapping shard ranges and recommends how overlaps can be repaired by shrinking into a single chosen path. Prompted user input or a '-y' option will then cause the appropriately modified shard ranges to be merged into the container DB. The repair command does not fix gaps in shard range paths and can therefore only succeed if there is at least one unbroken path of shards through the entire namespace. Also adds an analyze command that loads shard data from a file and reports overlapping shard ranges, but takes no action. The analyze command is similar to the repair command but reads shard data from file rather than a container db and makes no changes to the db. e.g.: swift-manage-shard-ranges <db-file-name> repair swift-manage-shard-ranges <shard-data.json> analyze to see more detail: swift-manage-shard-ranges -v <shard-data.json> analyze For consistency with the new repair command, and to be more cautious, this patch changes the user input required to apply the compact command changes to the DB from 'y' to 'yes'.
