Tests for materialized views that need a three-node cluster.

Note that most materialized-view functional tests can make due with a single
|

node, and belong cql-pytest. We also have topology_experimental_raft/
|
|
test_mv_tablets.py for tests that each needs a cluster of a different
|

size, and/or special Scylla parameters.
