Updated the supported methods of Calculator (#6)

1. Updated the supported methods of Calculator
2.1 Updated the `.js` to test it; The `.js` establishes `WS` connection to calculator service; so, it does not have to say `calculator.add`
2.2 Thunder on the otherhand when request was sent as `calculator.add`, it identifies `RustAdapter.so` as plugin library and send the method to be invoked as `add` to it.
3. Updated the calculator.json with other options available for out-of-process execution
