- Remove `testNewShard` and `setInitializedShards` because they violated the default engine workflow. The correct workflow is: first use `New()`, followed by `Open()`, and then `Init()`. As a result, adding new logic to `(*StorageEngine).Init` caused several tests to fail with a panic when attempting to access uninitialized resources. Now, all engines created with the test utils must be initialized manually. The new helper method `prepare` can be used for that purpose. - Additionally, `setInitializedShards` hardcoded the shard worker pool size, which prevented it from being configured in tests and benchmarks. This has been fixed as well. - Ensure engine initialization is done wherever it was missing. - Refactor `setShardsNumOpts`, `setShardsNumAdditionalOpts`, and `setShardsNum`. Make them all depend on `setShardsNumOpts`. Signed-off-by: Aleksey Savchuk <a.savchuk@yadro.com>
