Restore Cassandra port option

Browse Source 
This commit restores the port option that was removed in an earlier
milestone. Contact points that do not define a port already are
automatically transformed to include the one configured, with a default
matching Cassandra's default port.

This makes upgrades easier in the case a cluster uses consistent ports
everywhere.

Closes gh-19672

If the port is the same for all your contact points you can use a shortcut and only specify the host names, as shown in the following example:

TIP: Those two examples are identical as the port default to `9042`.
If you need to configure the port, use `spring.data.cassandra.port`.
You can also register an arbitrary number of beans that implement `DriverConfigLoaderBuilderCustomizer` for more advanced driver customizations.
The `CqlSession` can be customized with a bean of type `CqlSessionBuilderCustomizer`.
