Overview

Package expireddeletion contains the functions needed to run expired segment deletion

The expireddeletion.expiredDeleter implements the metainfo loop Observer interface allowing us to subscribe to the loop to get information for every segment in the metainfo database.

The expireddeletion chore will subscribe the deleter to the metainfo loop and delete any expired segments from metainfo.
