Instrumenting cassandra executeReactive method (#6441) 
It follows the
[issue](https://github.com/open-telemetry/opentelemetry-java-instrumentation/issues/6395#issue-1323561263)
I opened some days ago.

The `executeReactive` method use the same processor used by
`executeAsync` (see
[here](65d2c19c40/core/src/main/java/com/datastax/dse/driver/internal/core/cql/reactive/CqlRequestReactiveProcessor.java (L53)))
and wrap the callback in the `DefaultReactiveResultSet` publisher.

Here I'm simply overriding the `executeReactive` method doing the same
thing: call the already instrumented `executeAsync` method and wrapping
the callback using the `DefaultReactiveResultSet` publisher.

~~I did an upgrade of the `java-driver-core` library to have
`TracingCqlSession.java` extending the `ReactiveSession`. I have to
probably rename the `cassandra-4.0` module in `cassandra-4.14` but I'll
let you confirm this.~~ -> Cassandra-4.4 is enough.
