`GETRANGEHASH` request spawns `GETRANGE` requests if an object could not be
found locally. If the original request contains session, it can be static
and, therefore, fetching session key can not be performed successfully.
As the best effort a node could request object's range with its own key.

Stop child objects collection if the last returned object (the most "left"
object in the collected chain) starts exactly from the `GETRANGE`'s `from`
value.

That could happen if a node forwards request to a node that closed the
connection during the original object stream.

A container node is expected to have full "get" access to assemble the
object.
A non-container node is expected to forward any request to a container node.
Any token is expected to be issued for an original request sender not for a
node so any new request is invalid by design with that token.

Storage node should not provide NeoFS Object API service when it is
under maintenance.
Declare `Common` service that unifies behavior of all object operations.
The implementation pre-checks if node is under maintenance and returns
`apistatus.NodeUnderMaintenance` if so. Use `Common` service as a first
logical processor in object service pipeline.

Current spec allows denying GET_RANGE requests from other storage nodes.
However, GET should always be allowed and it is enough to perform
GET_RANGE locally

In previous implementation `ObjectService.Get` RPC handler failed with
`parent address in child object differs` while assembling the "big"
object. This was caused by the child check which required parent
reference to be set in all child objects. The check was impracticable
because not all elements of the split-chain have a link to the parent.
Make `execCtx.isChild` to return `true` if parameterized object has no
parent header in its own header.

In previous implementation node blocked any operation of local object
storage in maintenance mode. There is a need to perform some storage
operations like data evacuation or restoration.
Do not call block storage engine in maintenance mode. Make all Object
service operations to return `apistatus.NodeUnderMaintenance` error from
each local op.

After fixing version fields in forwarded requests, a node does not check
statuses since errors are not covered by direct call error checks.

Forwarded requests contained zero version in their meta header. It did not
allow responding with API statuses (`v0.0` version considered to be older
than `v2.11`) to the forwarding node and, therefore, did not allow analyzing
responses.

The client needs of the Object service are limited and change not often.
Interface changes of the client library should not affect the operation of
various service packages, if they do not change their requirements for
the provided functionality. To localize the use of the base client and
facilitate further support, an auxiliary package is implemented that will
only be used by the Object service.

`CommonPrm` structure has private key for remote operations.
It obtained in the beginning of request processing. However,
not every operation triggers remote calls. Therefore, key
might not be used. It is important to avoid early key fetching
because `TokenStore` now returns error if session token does not
exist. This is valid case when container nodes receive request with
session token (for ACL pass) and they should process request locally.

Forwarding mechanism resends original request. During split object chain traversal,
storage node performs multiple `object.Head` requests on each child. If request
forwarding happens, then `object.Head` returns object ID of the original request.
This produces infinite assembly loop.

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.

the storage node information required for communication. Return slice of
`Node` instances from `Traverser.Next` method. Fix compilation breaks in
