Feature/gmsh boundary flag for alugrid

See merge request !1672

The boudnary segment index flag is the default except if it's
overwritten for a specfific grid. This is currently done in ALU which
per default only works with DGF boundary flags.

Samuel Scherrer authored 5 years ago and Timo Koch committed 5 years ago

For gmsh we always want the intersection.boundarySegmentIndex as a
boundary flag, while for DGF file Alu grid needs to use the non-standard
intersection.impl().boundaryId().
