All error counting and hangling logic is present on the engine level. Currently, we pass engine metrics with shard ID metric to shard, then export 3 methods to manipulate these metrics. In this commits all methods are removed and error counter is tracked on the engine level exlusively. Signed-off-by: Evgenii Stratonikov <e.stratonikov@yadro.com>
