NOTE: T292310 covers the notification itself. This ticket covers writing a script to send the notifications.
Write a maint script in the [[ https://phabricator.wikimedia.org/T299924 | new image suggestions notifications extension ]] that sends image suggestions notifications to experienced users.
Image suggestions for unillustrated articles can be read from hdfs (see T299789, using `commonswiki_file` to get confidence scores) or Cassandra (T299885 ... possibly via an API)
 Each user who has not opted out of these notifications (see T292146) with >500 edits will get at most **two** notifications each time the script is run, where the notification
 is about a image suggestion for an unillustrated article on the user's watchlist
 where the confidence score of the suggestion is above **TBD**% (see T281582 and T283865)
 is **not** about an article that the user has previously received **any** image suggestion notification for
 prioritising articles this user has edited in the last 30 days (see T292312), then ordered randomly
**Note**: Scheduling the notification is covered in T300024
