Add support for vector CQL data type

[msmygit]

Both Astra DB and DSE 7.0 (public preview as of this writing) already supports vector as a CQL data type and OSS C* will soon support the same via CEP-30. CDC source connector should begin supporting this.

On Nov 6, 2023 5.0-alpha2 got released which contains support for vector

and... datastax/dse-server:7.0.0-alpha.2 which also got released 3 days back on Nov 13, 2023.

and... with Quarkus adding support to LangChain4j project, this will be even more compelling for AI developers.

This makes a ton of sense. We need to get a new release out with a more recent version of Quarkus anyway... an update to get any kind of vector support would be super-nice as well.
