Previously, storage engine ignored configured shards if they failed to open/init (with at least one successful). This behavior is unclear: if engine is configured to work with N shards, then all N shards must work, otherwise, the whole engine is broken and needs to be reconfigured. Immediately fail engine's `Open`/`Init` methods on any shard failure. With this, it's redundant to open/init shard concurrently, so they are processed one-by-one now. In the future, possibly, optional config flag will be added to ignore problem shards, but default behavior will be kept strict. Signed-off-by: Leonard Lyubich <[email protected]>
