title: Update ksql stream with new topic schema
body: <p>I write avro messages into kafka topic using schema registry.
  Then created stream based on the topic. The scream created with current schema.</p>
  
  <p>Then I add new field to the schema. The schema register updated, it's OK, but the stream stay with the first structure.</p>
  
  <p>Can I update the stream with new schema?</p>
  
  <p>It's problematic for me to drop and create the schema again because I have lot of other streams\tables that depend on it. The KSQL don't allow to drop stream with dependencies.</p>
