This allows things like this:

  parameters["krylov_solver"]["relative_tolerance"] = 1e-10

This sets the default value for all Krylov solver created after this.

We should make the same thing for other parametrized objects whenever
it is appropriate. It requires two minor changes:

1. Adding the parameter set as a nested set in GlobalParameters.cpp:

  this->add(KrylovSolver::default_parameters());

2. Initializing with the nested set in KrylovSolver.cpp:

  parameters = dolfin::parameters("krylov_solver");
