SpringBoot CassandraDataAutoConfiguration's constructor should not require a CqlSession connection

The constructor for CassandraDataAutoConfiguration requires a CqlSession connection (provided in CassandraAutoConfiguration) whether used or not. This should be better provided through @Bean method injection which are behind a @ConditionalOnMissingBean.

This means that applications with Cassandra libraries on the Classpath will automatically require a connection by default even when not used, and will fail to boot if a connection cannot be established.

Using Spring Boot 3.2.3

Ah realised that solution is still not quite right as the beans making use of CqlSession are by default not lazy initialized, unlike CqlSession itself. Feel free to close this ticket.
