@lpsaavedra Don't forget to set these parameters in the new parameter files!

…os-polymtl#1264) Description In PR chaos-polymtl#1211 a new parameter was introduced that allow to iterate intermediate GMG levels. This allows to choose a level as coarse grid and used there a GMRES iterative solver preconditioned by a MG. So far, only one parameter was present: mg int level, however, the parameters for the number of iterations and tolerances were being hardcoded. This PR changes that by using already existing GMRES parameters.. Testing I have tested this in the flow around a sphere case and seems to work just fine. Documentation The documentation was updated by adding a note that specifies the use of these parameters for this purpose as well. Former-commit-id: bf39a0d
