Support annotations in generated field

Let's say I have a class ExcelDto:

``` java
import com.google.auto.value.AutoValue;
import javax.xml.bind.annotation.*;
import java.util.List;

@XmlRootElement(name = "excel")
@XmlAccessorType(XmlAccessType.FIELD)
@AutoValue
public abstract class ExcelDto {

@XmlElementWrapper(name = "tables")
@XmlElement(name = "table")
public abstract List getTables();

public static ExcelDto create(List tables) {
return new AutoValue_ExcelDto(tables);
}
}
```

Now I wanted the generator to build an `AutoValue_ExcelDto` class, but with the field `tables` annotated like:

...

``` java
@javax.xml.bind.annotation.XmlTransient
private final List tables;
```

...

Is that possible, how to achieve this?
