aws2-ddb: cannot use `url-connection-client` if `quarkus-amazon-dynamodb` is in the classpath

See items 2 and 4 from this [PR](https://github.com/apache/camel-quarkus/pull/2988) for more details.

Currently it is not possible to use `url-connection-client` with `quarkus-amazon-dynamodb` because it creates runtime error, that both apache and non-apache clients are present together. Exclusion of apache client doesn't work, because aws-support extension requires it. (which could be possible to refactor)

Using `quarkus-amazon-dynamodb` also breaks `integration-tests/aws2` - it has to be investigated, whether it is possible to leverage `quarkus-amazon-dynamodb` and modify both test modules accordingly.
