title: protobuf timestamp: Use Java 8 time.Instant
body: <p>I'm using protobuf, and one of my message uses the <code>google.protobuf.Timestamp</code> type.</p>
  
  <p>When generating the Java-Code, the resulting protobuf classes use <code>com.google.protobuf.Timestamp</code>.</p>
  
  <p>Is there a way to tell protobuf to use the new Java 8 types (e.g. <code>time.Instant</code>) instead? I don't want the type conversion clutter my code, everywhere I use protobuf. Ideally, it is done inside the generated code itself.</p>
