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.

6f8c45d61b [#176] localstore: Change multiple access sync 
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.

6280d075b9 [#208] Remove childfree search attribute 
With updated specification of object related operation
we don't have this search attribute any more and we
should not use functions related to this attribute.

This commit breaks object service logic, however it will
be fixed later.

03fed8ca59 [#160] Update metabase with new root and phy flags processing 
Now root and phy (leaf) filters work like flags. They work with
any matcher and any value. So meta-storage sets `true` value for
all root and phy objects and puts them into separate bucket.

We also do not work with inversion anymore, so it either added
to the bucket or not. We don't need to store both options.
This is the reason `selectAll` function is changed a bit. Now
it performs some low-level parsing from primary bucket and root
bucket.
