Merged requested to merge bilke/ogs:petsc-utils into master
On PETSc config applications in general needed to call
MPI_Init(). Otherwise the application would crash. This prevented lots of utils from being enabled in such a config.
This MR checks if MPI is uninitialized and then uses serial vtk file IO. Now utils can be enabled on PETSc config.
