1. add setup, teardown hooks
2. move the managed mount setup and teardown to filesystem backend
3. remove this vague storage.js
we should convert storageApi into a real object, so we don't have to
keep passing apiConfig around
snapshot file tracks the snapshot directory. when app gets deleted,
the cleaner will remove the upstream snapshot directory when it runs.
cache files are used in rsync logic to track what was uploading into
snapshot in the previous run without needing to rescan upstream.
format is part of the backup target
in the future, if we want per-app format or schedule, we can add this
separately to the apps table itself. the full box backup can ignore
apps with a set backup target and use the latest backup (like an errored app).
the nice thing is restore will work correctly.
Cleaner to separate things from the backups table.
* icon, appConfig, appStoreIcon etc are only valid for archives
* older version cloudron does not have appConfig in backups table (so it
cannot be an archive entry)
the backup cleaner erroneously removes any "creating" state backups.
backups that are stuck are cleaned up elsewhere already (in the
backup retention logic with discardReason of "creating-too-long").
the missing backup logic is intended for any upstream lifecycle policies.
the main motivation is that id can be used in REST API routes. previously,
the id was a path and this had a "/" in it. This made /api/v1/backups/:backupId
not work.
