KAFKA-6105: load client properties in proper order for EndToEndLatency tool Currently, the property file is loaded first, and later a auto generated group.id is used: `consumerProps.put(ConsumerConfig.GROUP_ID_CONFIG, "test-group-" + System.currentTimeMillis())` so even user gives the group.id in a property file, it is not picked up. Change it to load client properties in proper order: set default values first, then try to load the custom values set in client.properties file.
