Add a swiftlint rule to prefer final classes

Summary: There were only 2 instances in which I had to add a disable comment for prefer_final_classes due to subclassing Used the following to add the final keyword (Adds final to any class that doesn't have final or open before it and doesn't have func after it) ``` find . -name '*.swift' | xargs perl -pi -e 's/(?<!final )(?<!open )(class (?!func).*\{)/final \1/g' ``` Reviewed By: samodom Differential Revision: D34119233 fbshipit-source-id: 963d64fefc1686095d0bfe18ac7cb9677606f4e6
