> When adding a new DC, keyspaces must be manually updated to replicate to the new DC.
 This is problematic for system_auth, as it cannot achieve LOCAL_ONE consistency (for a non-cassandra
user), until its replication options have been updated on an existing node.
> Ideally, system_auth could be set to an "All Nodes strategy" that will replicate it to
all nodes, as they join the cluster.  It also removes the need to update the replication factor
for system_auth when adding nodes to the cluster to keep with the recommendation of RF=number
of nodes (at least for small clusters).
