Harmonize data configuration

Browse Source 
Any classes that rely on Spring Data being on the classpath
have been moved under a data package.

Certain configuration properties have also been updated to
accurately reflect whether Spring Data is required for the
auto-configuration to work.

==== Connecting to Cassandra
You can inject an auto-configured `CassandraTemplate` or a Cassandra `CqlSession` instance as you would with any other Spring Bean.
The `spring.data.cassandra.*` properties can be used to customize the connection.
The `spring.cassandra.*` properties can be used to customize the connection.
Generally, you provide `keyspace-name` and `contact-points` as well the local datacenter name, 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`.
If you need to configure the port, use `spring.cassandra.port`.
[NOTE]
====
The Cassandra driver has its own configuration infrastructure that loads an `application.conf` at the root of the classpath.
Spring Boot does not look for such a file by default but can load one using `spring.data.cassandra.config`.
If a property is both present in `+spring.data.cassandra.*+` and the configuration file, the value in `+spring.data.cassandra.*+` takes precedence.

If a property is both present in `+spring.cassandra.*+` and the configuration file, the value in `+spring.cassandra.*+` takes precedence.
For more advanced driver customizations, you can register an arbitrary number of beans that implement `DriverConfigLoaderBuilderCustomizer`.
The `CqlSession` can be customized with a bean of type `CqlSessionBuilderCustomizer`.
