Tim Alby c1c23e4bee record last author id on document flush
This is a multi-steps process:
* get a update's `user_id` from the metadata
* store the `user_id` (`lastUpdatedBy`) and current date (`lastUpdatedAt`) for
  the document in Redis on every updates
* fetch `lastUpdatedAt` and `lastUpdatedBy` from Redis on document flush
* send the data to web to be persisted in Mongo
