When getting a role in the APE checker for the container services,
an error may be returned if network maps of the previous two epochs
don't have enough nodes to fulfil a container placement policy.
It's a logical error, so we should ignore it.

* `SignRequestPrivateKey` field should be initialized either within
`newUntrustedTarget` or within `newTrustedTarget`. Otherwise, all
requests are signed by local node key that makes impossible to perform
patch on non-container node.

Consider the following operations ordering:
1. Inhume(with tombstone A) --> add tombstone mark for an object
2. --> new epoch arives
3. --> GCMark is added for a tombstone A, because it is unavailable
4. Put(A) --> return error, because the object already has a GCMark
It is possible, and I have successfully reproduced it with a test on the
shard level. However, the error is related to the specific
_ordering_ of operations with engine. And triggering race-conditions like
this is only possible on a shard level currently, so no tests are
written.

There might be situation when context canceled earlier than traverser move to another part of the nodes.
To avoid this, need to wait for the result from concurrent put at each traverser iteration.

* Remove `relay` field from put streamer as it's no longer used;
* Fix initialization of `Relay` object writer parameter.

If local EC chunk found, but remote node is off, then `HEAD --raw` request
returns object not found.

* `Patch` can't be applied for non-regular type object (tombstones,
locks etc.)
* Complex object parts can't be patched. So, if an object has EC/Split
header, it won't be patched.

Created grpc connection should be established, so perform Healthcheck request
to check connection is ok.

* Tree and object service have the same log for checking APE. So,
this check should be moved to common package.

If slice is altered in `for` loop, we cannot use range over its
length: it may cause panic if slice gets shorter.

* Split the logic of write target initialization to different packages;
* Refactor patch and put services: since both service initialize the target
themselves.

Since Go 1.22 a "for" statement with a "range" clause is able
to iterate through integer values from zero to an upper limit.
