[etcd-backup-restore]

🏃 Others

• [USER] Compaction job will now throw warning instead of error if revisions are already compacted (#358, @shreyas-s-rao)
• [OPERATOR] Added '--etcd-snapshot-timeout' and '--etcd-defrag-timeout' CLI flags in 'server' and 'compact' subcommands (#361, @ishan16696)
• [OPERATOR] Updated number of chunks while uploading to never exceed the cloud provider limits. (#334, @abdasgupta)

📰 Noteworthy

• [OPERATOR] Snapshots are not stored under separate prefix (Backup-XXX) in backup storage. Instead, all of the snapshots are stored under v2 backup version prefix in a flat structure. (#301, @abdasgupta)
• [OPERATOR] Support for v1 backup version is still there but only for restoration and snapshot garbage collection. So backup storages that had v1 backup version and where snapshots were stored under separate prefix (Backup-XXX), can still be used with compaction sub command (as well as for restoration). However, the new snapshots will be stored under v2 backup version prefix. (#301, @abdasgupta)
• [OPERATOR] The support for the v1 backup structure with separate prefix (Backup-XXX) will be dropped in a subsequent release. (#301, @abdasgupta)
