Once SERVER-22338 is finished, we need to do another round of formatting and linting before making "scons lint" fail on JS formatting or linting errors.

We should also enable clang-format for JS formatting by default in these files:

1. https://github.com/10gen/mongo-enterprise-modules/blob/r3.3.3/.clang-format
2. https://github.com/mongodb/mongo/blob/r3.3.3/src/mongo/.clang-format
3. https://github.com/mongodb/mongo/blob/r3.3.3/jstests/.clang-format
