1. #107: Custom headers are also supported for the query (gRPC request)

   ClientConfig config = new ClientConfig.Builder()
       .host("https://us-east-1-1.aws.cloud2.influxdata.com")
       .token("my-token".toCharArray())
       .database("my-database")
       .headers(Map.of("X-Tracing-Id", "123"))
       .build();
   
   try (InfluxDBClient client = InfluxDBClient.getInstance(config)) {
       //
       // your code here
       //
   } catch (Exception e) {
       throw new RuntimeException(e);
   } 

2. #108: Custom headers can be specified per request (query/write):

   ClientConfig config = new ClientConfig.Builder()
       .host("https://us-east-1-1.aws.cloud2.influxdata.com")
       .token("my-token".toCharArray())
       .database("my-database")
       .build();
   
   try (InfluxDBClient client = InfluxDBClient.getInstance(config)) {
       //
       // Write with custom headers
       //
       WriteOptions writeOptions = new WriteOptions(
           Map.of("X-Tracing-Id", "852")
       );
       client.writeRecord("mem,tag=one value=1.0", writeOptions);
       
       //
       // Query with custom headers
       //
       QueryOptions queryOptions = new QueryOptions(
           Map.of("X-Tracing-Id", "852")
       );
       Stream<Object[]> rows = client.query("select * from cpu", queryOptions);
   
   } catch (Exception e) {
       throw new RuntimeException(e);
   }
