Verify and fix property overrides in all operators

[razvan]

Issue checklist

Verify (and fix if necessary) that property overrides (env, conf) work as intended in all operators.

There have been reports that this is not the case. Examples:

• HDFS env overrides not working correctly hdfs-operator#497
• Add test to reproduce configOverrides at role level bug trino-operator#556

This issue tracks the state of this feature across all operators:

• airflow-operator
• commons-operator
• druid-operator
• edc-operator
• hbase-operator
• hdfs-operator
• hello-world-operator
• hive-operator
• kafka-operator
• listener-operator
• nifi-operator
• opa-operator
• secret-operator
• spark-k8s-operator
• superset-operator
• trino-operator
• zookeeper-operator
