[Dune-devel] newer compilers in the CI system

[Martin Nolte]

Hi Ansgar,

it would be great to test with newer compilers, especially gcc-7. Dropping 
Debian 8 also seems reasonable for the master.

However, we explicitly support Debian 8 for the 2.5 release series, so here at 
least Debia 8 + gcc should be tested, as it also checks for CMake 3.0.

Before dropping tests for older systems, I would suggest to rethink our compiler 
and CMake requirements. If we drop Debian 8, I guess noone will test with CMake 
3.0. In my opinion, we should definitely test with the lowest version of CMake 
we support.

Best,

Martin
