ec04e787aa [#922] storage engine: Support operation blocking
There is a need to disable execution of local data operation on storage
engine in runtime. If storage engine ops are blocked, node will act like
always but all local object operations will be denied.

Implement `BlockExecution` / `ResumeExecution` methods on `StorageEngine`
which blocks / resumes the execution of data ops. Wait for the completion of
all operations executed at the time of the call. Return error passed to
`BlockExecution` from all data-related methods until `ResumeExecution` call.
Make `Close` to block operations as well.

1b51dcf8a4 [#546] engine/inhume: Fix incorrect Inhume behavior for root objects
If object to be inhumed is root we need to continue first traverse over the
shards. In case when several children are stored in different shards,
inhuming object in a single shard leads to appearance of inhumed object in
subsequent selections. Also, any object can be already inhumed, and this
case is equivalent to successful inhume.

Do not fail on `object.ErrAlreadyRemoved` error. Continue first iterating
over shards if we detected root object (`SplitInfoError`).

so it is better to locate such functions in common

a2c2241356 [#379] storage engine: Inhume object in one shard
In previous implementation StorageEngine.Inhume operation forced Shard
.Inhume call on all internal shards. There is a need to inhume object in a
single shard. To achieve this, Inhume operation is performed in next steps:

 1. iterate over sorted shards, check object presence through Exists call;
 2. if object exists at any shard in step 1 => inhume it and return on
    success;
 3. if no shards contain the object => iterate over sorted shards again and
    try to inhume the object at first possible shard;
 4. if all Inhume calls are failed => return an error.

the weights of the shards change as a result of write operations.
With the transition to static weights of shards, it is no longer
necessary to lock the global mutex during the execution of operations.
However, since the set of engine shards is dynamic, there is still a
need to control multiple access to this set. The same mutex is used
for synchronization.
