> PipelineOptions currently serializes information about all getter/setter pairs on interfaces
which don't extend PipelineOptions.
> For example:
> {code:java}
> interface Foo extends PipelineOptions, Bar {
>   String getFoo();
>   void setFoo(String value);
> }
> interface Bar {
>   String getBar();
>   void setBar(String value);
> }
> {code}
> The serialization of the above (when both *foo* and *bar* are set) will produce JSON
where we only include display data for *foo* but data for both *foo* and *bar*. During validation
of an interface in *PipelineOptionsFactory*, we should throw an error if one of the users
interfaces doesn't extend *PipelineOptions* (note that we should ignore the HasDisplayData
interface).
