Convert MPI error type to PETSc error with string message for all MPI calls

Now PETSc examples will ONLY return PETSc error codes and never MPI error codes directly so we can understand and post-process their
errors better.

The test harness will now automatically retry tests that fail with MPI, this may help with Intel MPI that produces
seemingly random failures.

DM: Change examples to use DMAddBoundary() instead of PetscDSAddBoundary()
- Now you have to call DMCopyDS() after labels have been established on the coarse DM
- Also, p4est setup has to have happen
