efb39a5665
This change modifies the swift-ring-builder and introduces new format of sub-commands (search, list_parts, set_weight, set_info and remove) in addition to add sub-command so that hostnames can be used in place of an ip-address for the sub-commands. The account reaper, container synchronizer, and replicators were also updated so that they still have a way to identify a particular device as being "local". Previously this was Change-Id: Ie471902413002872fc6755bacd36af3b9c613b74 Change-Id: Ieff583ffb932133e3820744a3f8f9f491686b08d Co-Authored-By: Alex Pecoraro <alex.pecoraro@emc.com> Implements: blueprint allow-hostnames-for-nodes-in-rings
