Add quarkus profile 'kafka-events-support' to data index images

Recently, the Data Index has introduced two working modes depending on the supported events: Kakfa and Http. We are using the quarkus.profile property to switch ON them

Regarding smallrye restrictions the default working mode have to be the Http, that depending on the needs can be switch to the Kafka one.

In order to maintain backward compatibility,  the kafka event support have to be the one enabled by default.

To achieve that, the environment property QUARKUS_PROFILE needs to have the value 'kafka-events-support' in the Data Index generated images by default.
