Message:

New way of running the petsc solver, that provides more flexibilty.
We have a new petscoptions field in the model, that can be filled
with petsc options, instead of the solver_string, which disappers.
The petscoptins gets resolved into a petscrc string (for serial runs)
and a petsc.rc file (for parallel runs) at runtime. The petscrc string
acts the same way than the solver_string. But the petsc.rc file acts
in a different way. Itt is loaded at runtime, when first doing Petsc Initialize.
This allows tweaking and rerunning of the same deck, each time using different
options.
