MINOR: Disable JmxTool in kafkatest console-consumer by default (#7785)

Do not initialize `JmxTool` by default when running console consumer. In order to support this, we remove `has_partitions_assigned` and its only usage in an assertion inside `ProduceConsumeValidateTest`, which did not seem to contribute much to the validation.
