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.

All error counting and hangling logic is present on the engine level.
Currently, we pass engine metrics with shard ID metric to shard, then
export 3 methods to manipulate these metrics.
In this commits all methods are removed and error counter is tracked on
the engine level exlusively.

- `reportShardErrorBackground()` no longer differs from
`reportShardError()`, reflect this in its name;
- reuse common pieces of code to make it simpler.

Target container ID is taken from tombstone: cmd/frostfs-node/object.go:507
Also object of type `TOMBSTONE` contains objectID, so tombstone and
tombstoned object must have the same containerID.

* `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.

For EC chunks need to return EC parent object ID as
EC chunks don't have own attributes but inherit parent's.

FSTree file counter used by writecache. As writecache has now only one
storage, so it is required to use real object size to get writecache
size more accurate than `count * max_object_size`.

to iterate through integer values from zero to an upper limit.
