description:
Cleanup KrylovSolver:

 - Remove setFoo() functions in public interface
 - Cleanup and restructure implementation

Please check that everything looks ok. I think it the code is easier
to follow now, but I may be wrong.

In particular, check that everything works wrt boo set_pc (I removed it).

description:
- Remove KrylovSolver::setRtol() etc., replaced by parameters.
- Zero pivot drop tolerance removed, use KrylovSolver::solver()
  to get the PETSc KSP pointer for advanced options

description:
Add new global parameters for Krylov solver:

    "Krylov relative tolerance"  1e-9
    "Krylov absolute tolerance"  1e-20
    "Krylov divergence limit"    1e4
    "Krylov maximum iterations"  10000
    "Krylov report iterations"   true
    "Krylov monitor convergence" false

Old function setRtol() etc still there but will be removed
