> CASSANDRA-16525 avoids trying to calculate the cluster min version if 
> gossiper is not enabled.
> This makes us memoize the wrong version for up to a minute causing us to send 
> 4.0-messages to 3.0 nodes, for example in 
> [ColumnFilter|https://github.com/apache/cassandra/blob/05beda90a9206db165a3997a736ecb06f8dc695e/src/java/org/apache/cassandra/db/filter/ColumnFilter.java#L210]
> This was discovered by python upgrade dtests,
