Description

When calculating paired view replicas on MV writes, we filter out base and view replicas that aren't in the local datacenter.

If we are using SimpleStrategy, this filtering is incorrect, since our replica placement is not datacenter aware.

We should behave the same as DC-aware consistency levels and only perform this datacenter-aware filtering if the replication strategy is an instance of NetworkTopologyStrategy.
