Currently, LOCK object, sign in metabase about lock and locked object can be placed on separate shards.
This leading to race between policer and gc.

To solve this for EC object the exist method returns lock marker, this forces lock action when we put reconstructed chunk.
The same is valid for regular objects when policer recovering copy.

In scope of this task, need to consider the option of moving gc form Shard to StorageEngine level.
