Simplify integration tests.

1. Remove SolverConfig, this was a wrapper
   around Solver::Options. As we experiment
   with more Solver::Options, it became a hurdle.

2. Updated generate_bundle_adjustment_tests.py to use
   Solver::Options directly.
3. Update system_test to use Solver::Options.

NOTE: generate_bundle_adjustment_tests.py changes are a bit
gunky, but I tried to minimize the changes in this CL
as I am going to introduce new test cases and that
is going to significantly change this file.
