Drop sent_notifications.reply_key unique index ASYNC
What does this MR do and why?
Schedule index to be dropped over the weekend in .com as it's a very large index
The entire table is soon to be dropped as part of the effort to partition it in #417233. Index already dropped in the partitioned table !214140 (merged)
We no longer write/read from that table or index
no index reads after we stopped reading from the old table
