Problem

After #6917 it should now be possible to clear up all deprecation warnings by: Replacing `update()` with `updateOne()`, `updateMany()`, or `replaceOne()` Replacing `remove()` with `deleteOne()` or `deleteMany()` Setting `mongoose.set('useFindAndModify', false);` Setting `mongoose.set('useCreateIndex', true);` * Setting `mongoose.set('useNewUrlParser', true);` Need a docs page to summarize this.

Solution: Docs page for how to fix deprecation warnings

Low Risk

I set `mongoose.set('useCreateIndexes', true)` and still get `DeprecationWarning: collection.ensureIndex is deprecated. Use createIndexes instead`. I've tried it before and after `mongoose.connect()`.
