ENTMQST-2030 - kafka-ack reports javax.management.InstanceAlreadyExistsException: kafka.admin.client:type=app-info,id=<client_id>with client.id set

Description

If the bin/kafka-acls.sh utility is used in combination with the --bootstrap-server parameter to add or remove an ACL, the operation is successful but a warning is generated. The reason for the warning is that a second AdminClient instance is created. This will be fixed in a future release of Kafka.
