URL: https://github.com/apache/pulsar/issues/11904


   **Is your enhancement request related to a problem? Please describe.**
   It's not possible to serialize/deserialize `Schema.KeyValue` in the python client. In particular the debezium source will return a bytes array.
   
   A quick workaround is to do 
   ```python
   key_size = int.from_bytes(msg[:4], 'big')
   event_key = json.loads(msg[4: key_size + 4])
   value_size = int.from_bytes(msg[key_size + 4: key_size + 8], 'big')
   event_value = json.loads(msg[key_size + 8: value_size + key_size + 8])
   ```
   where `event_key` and `event_value` are the json key and value of the message.
   
   **Describe the solution you'd like**
   It should be possible to define the serialization by importing a `KeyValue` schema from the `schemas` module.
