34a259d5c0 [#220] blobstor: Support zero shallow depth of blobovnicza tree 
There is a need to support single blobovnicza in blobovnicza tree. This can
be achieved with a width of 1, and a depth of 0 or 1. With depth = 1 one
redundant directory is created, inside which there is a blobovnicza. If the
depth is zero, the blobobnivza will be in the root path. Fix negative
capacity in iterateDeepest method with zero depth.

With exist check we should index parent first, because

parent will return true even if it was not indexed yet.

Also this commit makes one db.Update instead of two for
parent and child.

In previous implementation each operation on local storage
locked engine mutex. This was done under the assumption that
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.

df558cbe6b [#176] shard: Get rid of using the global RW lock 
In previous implementation each shard operation locked
RW shard mutex. With this approach RW operations were executed
one-by-one and blocked the execution of RO operations.

73494c4bbc [#176] localstore: Fix Get with non-zero length 
GetPrm has WithPayloadRange option to specify the requested
payload range. In previous implementation StorageEngine.Get
method ignored this option. From now zero length matches
full payload request.
