Paul Luse 6da9799917 Add Storage Policy Support to Container Sync
Have container sync get its object ring from POLICIES now,
update tests to use policy index from container_info and pass
that along for use in ring selection.

This change also introduced the option of specifiying in the cluster info
which of the relam/cluster's is the current realm/cluster.
