There is a need to process public keys of the placement result.
Implement `Node.PublicKey` method which returns storage node's key announced
in netmap.

In previous implementation `placement.Traverser.Next` method returned slice
of `network.AddressGroup` elements. There is a need to process keys of
storage nodes besides network addresses for intra-container communication.
Wrap `network.AddressGroup` in a new type `placement.Node` that summarizes
the storage node information required for communication. Return slice of
`Node` instances from `Traverser.Next` method. Fix compilation breaks in
dependent packages.

Make placement `Traverser.Next` method to return ``[]network.AddressGroup`
in order to support multiple addresses of the storeage nodes.

`network.Address` structure in most cases created once and used read-only.
Replace `AddressFromString` function with `Address.FromString` method with
the same purpose and implementation. Make all libraries to work with value.

This function converts 2-dimension array of container nodes
into single dimension array. Useful when we need to iterate
over whole container.

In previous implementation parent object header finalized twice in size
limiter + formatter. On the one hand, this added redundant action, on the
other hand, it could provoke a difference in the headers of the linking and
the last part. Change formatter to finalize parent header if it does not
container the signature. Change size limiter to reuse parent header after
last child finalization in linking child.

In previous implementation linking object inherited only ID of the parent
object. From now it inherits full header like last child.

In previous implementation child objects inherited parent attributes after
split-transformation, which was redundant. From now attributes are not
inherited.

In previous implementation placement traverser processed incorrectly with
local placement build. Also entity incorrectly traversed the placement
vectors for fixed number read operations until success. The erroneous
behavior was due to the use of a vector number of successes instead of
a scalar number in these scenarios.

Refactored pkg/netmap package provides JSON converters for
NodeInfo and PlacementPolicy structures, that has been used
by client applications.
It also updates Node structure itself so it is a part of
grpc <-> v2 <-> pkg conversion chain.

In previous implementation InitRelations call in payload size limiter was
called in write chunk method. This provoked clearing the split header in
children starting from the second.
Replace InitRelations call to the 1st child allocating stage.

In previous implementation payload size limiter panicked in case of payload
emptiness. It was caused by the component waiting for at least one write of
a part of the payload.
Fix NPE occurrence with internal initialization after the WriteHeader call.

In previous implementations object size limiter left checksums of parent
object payload unset. This was caused by the closure that written calculated
checksums to the child object instead of parent one.
Construct payload checksum writers in separate function in order to prevent
closure bug.

are equal to counts of corresponding replicas. Make traverser to take into
account select count of all replicas.

Define object writer interface. Implement payload size limiter that
restricts payload size of the object. Implement object format moulder that
fill verification fields and finalizes object structure.
