-ksp_converged_use_initial_residual_norm -
Notes:
Use KSPSetTolerances() to alter the defaults for rtol, abstol, dtol.
The precise values of reason are macros such as KSP_CONVERGED_RTOL, which
are defined in petscksp.h.
If the convergence test is not KSPConvergedDefault() then this is ignored.
If right preconditioning is being used then B does not appear in the above formula.
