Sensitivity code is stale and broken

[lazyoracle]

Describe the bug

Code for Sensitivity Analysis in c3/optimizers/sensitivity.py is broken since it has not been updated with the rest of the codebase.

To Reproduce

python c3/main.py test/sensitivity.cfg will throw a bunch of errors due to stale config files and stale code.

Expected behavior

• Sensitivity Analysis has significant overlap with Model Learning code, in that they use the same goal function. Ideally, the SET class should be derived from the Model Learning C3 class, re-implementing and extending as required
• run Sensitivity Analysis from the CLI with a working config file
• run Sensitivity Analysis in an interactive notebook
• Tests to check that code works as expected (this would require some way to quantify that sensitivity analysis is working, because right now it seems the only way to do that is look at plots)
• Module level docstrings
• Tutorial style documentation (either as a part of or following the Model Learning docs)

Additional context

Implementing SET as derived from C3 might either involve making a new class derived from the base Optimizer which is then derived by both C3 and SET or leaving C3 as is and just deriving SET from it. This will depend on how different the two classes are.
