-------------------------------------------------------------------
Can we also standardize the tests to use the default values - that is, from 32 to the new defaults (16 {{num_tokens}} with {{allocate_tokens_for_local_replication_factor=3}} uncommented).

> For reasons highlighted in CASSANDRA-7032, the high number of vnodes is not necessary. It is very expensive for operations processes and scanning. Its come up a lot and its pretty standard and known now to always reduce the num_tokens within the community. We should just lower the defaults.
