Updated license changes for community and enterprise flavours of Confluent Kafka (0b33a2c)

Use of Community version is encouraged for testing purposes only. It is highly recommended to use Confluent Enterprise for production Kafka clusters. The default service config installs the enterprise confluent kafka with no license and can be run for the trial period of 30 days. However, it is possible to update the license afterwards. Check Add Enterprise License section for more details. To install the community version see Switching to Confluent Community section.

Upgrade the base tech version of Confluent Kafka to 5.4.0. See Confluent Kafka’s Release Notes for 5.4.0 for details.
Updated the SDK to version 0.57.3
- #3215 is a major bug-fix since v0.57.0. Frameworks are recommended to upgrade to v0.57.3 and issue pod replace commands to exisiting deployments to mitigate the risks. Existing procedures for migrating a existing service to the quotated role should be followed.
Updated the scheduler JRE to v11.

Confluent Kafka 5.4.0 introduces [KAFKA-7335] - Store clusterId locally to ensure broker joins the right cluster, which means that kafka cluster will store the clusterId locally so that it does not join the wrong zookeeper cluster accidentally. Therefore, if your kafka service is connected to default DC/OS zookeeper, changing the zookeeper path is not permitted. Please check here for more information.

Update the base tech version of Confluent Kafka to 5.3.1.
