title: how to create multiple EmbeddedKafka beans on the same test spec
body: <p>How to create multiple EmbeddedKafka, right now i have defined two topics on EmbeddedKafka.</p>
  <pre><code>@EmbeddedKafka(
      partitions = 1,
      topics = [Constants.TEST_TOPIC_one, Constants.TEST_TOPIC_two],
      controlledShutdown = false,
      brokerProperties = [
          &quot;offsets.topic.replication.factor=1&quot;,
          &quot;transaction.state.log.replication.factor=1&quot;,
          &quot;transaction.state.log.min.isr=1&quot;
      ]
  )
  but i need to have two instance like below,
  
  @EmbeddedKafka(
          partitions = 1,
          topics = [Constants.TEST_TOPIC_one],
          controlledShutdown = false,
          brokerProperties = [
              **&quot;offsets.topic.replication.factor=1&quot;,
              &quot;transaction.state.log.replication.factor=1&quot;,
              &quot;transaction.state.log.min.isr=1&quot;**
          ]
      )
  
  @EmbeddedKafka(
          partitions = 1,
          topics = [Constants.TEST_TOPIC_two],
          controlledShutdown = false,
          brokerProperties = [
              **&quot;offsets.topic.replication.factor=2&quot;,**
              &quot;transaction.state.log.replication.factor=1&quot;,
              &quot;transaction.state.log.min.isr=1&quot;
          ]
      )
  </code></pre>
  <p><strong>in the above block i will be changing replication.factor</strong></p>
