Subject: [PATCH] Add auto_compaction for maintenance etcd (#562)

Automate the maintenance of etcd cluster. Namely, the addition of automatic compression of the etcd database.

> Since etcd keeps an exact history of its keyspace, this history should be periodically compacted to avoid performance degradation and eventual storage space exhaustion.

More detail here: https://etcd.io/docs/v3.5/op-guide/maintenance/
