Review comment:
Could you explain how this would work? Marking this as ```@Nullable``` would
not help circumvent the issue that ```Headers``` interface would still need to
be on the classpath. To verify, I made the requested changes and I receive the
following runtime error:
```
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/kafka/common/header/Headers
at
org.apache.beam.sdk.io.kafka.KafkaUnboundedSource.getOutputCoder(KafkaUnboundedSource.java:142)
```
When using kafka-clients 0.10.1.0. The ```Headers``` interface is only
available post 0.11.0.0.
