title: How to reset offset to beginning in spring cloud kafka binder
body: <p>I am using spring cloud kafka binder to read the data to KStream. While reading the data from one of the topic, i need to read from beginning. </p>
  
  <p>I have tried to set kafka offset reset and start offset properties. But, could not find any references. </p>
  
  <p>Could you please help me providing any sample application.yaml to reset the offset, so that i can consume messages from topic from the beginning</p>
  
  <p>Adding application.yaml that i have used:</p>
  
  <pre><code>spring.cloud.stream.bindings.input:
    destination: input-topic1
    consumer:
      useNativeDecoding: true
      headerMode: raw
  spring.cloud.stream.bindings.output:
    destination: output-topic
    producer:
      useNativeDecoding: true
      headerMode: raw
  spring.cloud.stream.bindings.beginningInput:
    destination: beginning-topic
    consumer:
      useNativeDecoding: true
