Add Composite Ring Functionality * Adds a composite_builder module which provides the functionality to build a composite ring from a number of component ring builders. * Add id to RingBuilder to differentiate rings in composite. A RingBuilder now gets a UUID when it is saved to file if it does not already have one. A RingBuilder loaded from file does NOT get a UUID assigned unless it was previously persisted in the file. This forces users to explicitly assign an id to existing ring builders by saving the state back to file. The UUID is included in first line of the output from: swift-ring-builder <builder-file> Background: This is another implementation for Composite Ring [1] to enable better dispersion for global erasure coded cluster. The most significant difference from the related-change [1] is that this solution attempts to solve the problem as an offline tool rather than dynamic compositing on the running servers. Due to the change, we gain advantages such as: - Less code and being simple - No complex state validation on the running server - Easy deployments with an offline tool This patch does not provide a command line utility for managing composite rings. The interface for such a tool is still under discussion; this patch provides the enabling functionality first.

__RINGFILE__, build version 4, id __BUILDER_ID__
swift-ring-builder output corrected for ipv6 Adjusted width of ip and port columns in swift-ring-builder command output to dynamically span to the longest ip or the longest port in the devices list. Also combined the port and ip address columns for better visual clarity. Took care of ipv6 format [ipv6]:port Modified the corresponding test case with expected output.
