merge upstream changes from 2.0.2

[briangough]

I needed a stable hash for the v2.0.2 changes for the Server Pro release.
I created this by merging the upstream v2.0.2 into our fork.
I added @Seinzu's commit f3d6794 to fix the lint errors.
Looking at the git log the commits are in the right order.

Closing this PR as we moved away from our fork of multer to using a patch file.
