Test that our property defaults align with Cassandra's defaults

[wilkinsona]

See #24189 (comment) for background. The default values of some of our properties are out of sync with Cassandra's own defaults. We should add some tests to make sure that they're aligned, similar to those that we have for other auto-configuration.

This seems to be resolved via #25130.

Indeed it is. Thanks, @izeye.
