All objects in NeoFS must have owner ID. In previous implementation Object
Delete service handler set owner ID from request session token. If removal
was executed w/o a session, object with tombstone was prepared incorrectly.
In order to fix this node should set its own ID and become an owner of the
tombstone object.
Extend `NetworkInfo` interface required by Object.Delete handler with
`LocalNodeID` method which returns `owner.ID` of the local node. Implement
the method on `networkState` component of storage node application which is
updated on each node state change in NeoFS network map. Set owner returned
by `LocalNodeID` call as tombstone object's owner in Delete handler.

In previous implementation node returns "access denied" on Object.Put with
object with unset owner. Although object owner must be set, its absence
should not be considered as access error. The same applies to sender key.
Check owner ID and public key emptiness only if sticky bit is set.

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.

object. While object is signed by session token, the message itself
should be signed by the node key.

Session token can be present in both object header and
request meta header. They are the same during initial object
placement.
At the object replication, storage node puts object without
any session tokens attached to the request. If container's eACL
denies object.Put for USER role (use bearer to upload), then
replication might fail on objects with session tokens of the
signed by container owner. It is incorrect, so use session
token directly from request meta header.

There is a need to check if public key in the RPC response matches the

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 Object service's handler returned const error in
case of failure (full or partial) of PUT operation. This did not even allow
us to roughly guess what the reason is. Not as a complete solution, but to
alleviate some cases where all nodes in a container return the same error,
it is suggested to return the error of the last server that responded.
Return latest server error from placement loop of `iteratePlacement` method
of `distributedTarget` type.

Some software components regulate the way of working with placement arrays
when a local node enters it. In the previous implementation, the locality
criterion was the correspondence between the announced network address
(group) and the address with which the node was configured. However, by
design, network addresses are not unique identifiers of storage nodes in the
system.
Change comparisons by network addresses to comparisons by keys in all
packages with the logic described above. Implement `netmap.AnnouncedKeys`
interface on `cfg` type in the storage node application.

In previous implementation Container service handlers didn't cache the
results of `Get` / `GetEACL` / `List` operations. As a consequence of this,
high load on the service caused neo-go client's connection errors. To avoid
this there is a need to use cache. Object service already uses `Get` and
`GetEACL` caches.
Implement cache of `List` results. Share already implemented cache of Object
service with the Container one. Provide new instance of read-only container
storage (defined as an interface)to morph executor's constructor on which
container service is based. Write operations remained unchanged.
