Merge branch 'feature/vtkwriter-polyhedron' into 'master'

Polyhedron cells for VTKWriter.

This feature implements the support for polyhedrons in VTKWriter. This MR depends on !103 (merged) .

See merge request !105 (merged)

Added 3 commits:

• c357ac6d...57877ad1 - 2 commits from branch releases/2.5
• 8ff4e261 - Merge branch 'feature/vtkwriter-polyhedron' into 'master'

Compare with previous version

I rebased the merge request on the current releases/2.5 branch so the CI tests should pass (which I would like to see before merging it).

Enabled an automatic merge when the build for 8ff4e261 succeeds

Sounds good. Thanks.
