As described in https://github.com/scylladb/scylladb/issues/8638, we're moving away from `SimpleStrategy`, in the future it will become deprecated. We should remove all uses of it and replace them with `NetworkTopologyStrategy`. This change replaces `SimpleStrategy` with `NetworkTopologyStrategy` in all unit tests, or at least in the ones where it was reasonable to do so. Some of the tests were written explicitly to test the `SimpleStrategy` strategy, or changing the keyspace from `SimpleStrategy` to `NetworkTopologyStrategy`. These tests were left intact. It's still a feature that is supported, even if it's slowly getting deprecated. The typical way to use `NetworkTopologyStrategy` is to specify a replication factor for each datacenter. This could be a bit cumbersome, we would have to fetch the list of datacenters, set the repfactors, etc. Luckily there is another way - we can just specify a replication factor to use for or each existing datacenter, like this: ```cql CREATE KEYSPACE {} WITH REPLICATION = {'class' : 'NetworkTopologyStrategy', 'replication_factor' : 1}; ``` This makes the change rather straightforward - just replace all instances of `'SimpleStrategy'', with `'NetworkTopologyStrategy'`.
