It is unsafe to restrict the sync nodes for repair to the source data center if it has too low replication factor in network_topology_replication_strategy, or if other nodes in that DC are ignored.
Also, this change restricts the usage of source_dc to `network_topology` and `everywhere_topology`
strategies, as with simple replication strategy
there is no guarantee that there would be any
more replicas in that data center.
