Title: Use fastAMG solver as default linear solver for upscaling applications

The fast AMG solver provided by dune-istl and @blattms is tested on realistic cases and shown to be generally faster and more roboust than the previous solver. We therefore set this to default. Documentation on available linear solvers are updated.
