[Dune] warning: 'boundaryId' is deprecated

[Oswald Benedikt]

Dear Dune, by what should I replace the member function boundaryId ?
The compiler complains about it as 'warning: 'boundaryId' is deprecated'.

The method is only really marked deprecated in the extended paragraph
of the documentation.

Thanks and have a great day! Benedikt
