URL: https://github.com/apache/beam/issues/26545

   ### What would you like to happen?
   
   BigQuery provides the functionality of labelling queries. It is beneficial when it comes to distinguishing two similar queries and distinguishing their costs. (of course when it is impossible to do it any other way)
   
   Unfortunately, it is impossible to set these labels right now for queries that read the data with the BigQueryIO class:
   ```
   pipeline.apply("Read rows", BigQueryIO.readTableRows().fromQuery(sql).usingStandardSql());
   ```
   
   It would be perfect to be able to do something like this: 
   ```
   pipeline.apply("Read rows", BigQueryIO.readTableRows()
       .fromQuery(sql)
       .withLabel("label1", "value1")
       .withLabel("label2", "value2")
       .usingStandardSql());
   ```
   
   As far as I know, this functionality is available in the Python version of this IO connector. I hope it will be doable for the Java connector as well.
