Description

This ticket adds a maximum replication factor guardrail to ensure safety when creating or altering key spaces. The replication factor will be applied per data center. The ticket was prompted as a user set the replication factor equal to the number of nodes in the cluster. The property will be added to guardrails to ensure consistency.
