I've been reading documentation on how to setup backups for mongodb using the mongodb operator. This page: https://www.percona.com/doc/kubernetes-operator-for-psmongodb/backups.html describes adding a `schedule` section and adding a `keep` property.
But, looking at other documentation pages, and the example code, backup scheduling should use a `tasks` section, and there's no other mention of a `keep` property. I'm not a go expert by any means, but looking at the code, it seems like maybe this `keep` feature doesn't exist yet.
Is there another way to only keep ## number of backups from scheduled backups? This feature would be really useful, so I don't have to periodically go in and cleanup ancient backups.
