// deleteLegacyPrefixes removes old kvstore prefixes of non-persistent keys
// which have been used in the past but have been obsoleted since. We remove
// them on agent start to ensure that as users upgrade, we do not leave behind
// stale keys
//
// Rules:
// - For non-persistent state, obsoletd prefixes can be deleted as soon as the
// prefix has been declared obsolete
//
// - For persistent configuration stored in the kvstore, a forward upgrade
// path must be created which automatically removes the old keys on successful
// translation.
