Currently, under a mixed load one failed PUT can lead to closing
connection for all concurrent GETs. For PUT it does no harm: we have
many other nodes to choose from. For GET we are limited by `REP N`
factor, so in case of failover we can close the connection with the only
node posessing an object, which leads to failing the whole operation.

The problem is that accidental timeout errors can make us to ignore
other nodes for some time. The primary purpose of the whole ignore
mechanism is not to degrade in case of failover. For this case,
closing connection and limiting the amount of dials is enough.

Missing `ReportError` method did not allow casing multi-client interface to
`errorReporter` interface and dropping broken connections.
`replicationClient` embeds that interface, and it is widely used across
node's code. Embedded interface does not allow casting its parent structure
to `errorReporter` and breaks multi client error reporting logic.
Multi-client scheme is extremely hard to maintain, it makes unpredictable
casts and does not allow tracking code flow, so it will be refactored in the
future anyway.

Previously, node could get an "infinite" small object: it could be expired
and thus could not be flushed (update its storage ID) to metabase => could
not be marked as flushed => node never removes such object and repeat all
the cycle one more time. If object exists and is not marked with GC (meta
returns `ErrObjectIsExpired`, not `ObjectNotFound` and not
`ObjectAlreadyRemoved`), its ID is safe to update _in the same_ bbolt
transaction.

Currently, DELETE service sets tombstone expiration epoch to
`current epoch + 5`. This works less than ideal in private networks
where an epoch can be e.g. 10 minutes. In this case, after a node is
unavailable for more than 1 hour, already deleted objects have a chance
to reappear.

LRU `Peek`/`Contains` take LRU mutex _inside_ of a `View` transaction.
`View` transaction itself takes `mmapLock` [1], which is lifted after tx
finishes (in `tx.Commit()` -> `tx.close()` -> `tx.db.removeTx`)
When we evict items from LRU cache mutex order is different:
first we take LRU mutex and then execute `Batch` which _does_ take
`mmapLock` in case we need to remap. Thus the deadlock.

To achieve high performance we must choose proper values for both
batch size and delay. For user operations we want to set low delay.
However it would prevent tree synchronization operations to form big
enough batches. For these operations, batching gives the most benefit
not only in terms of on-CPU execution cost, but also by speeding up
transaction persist (`fsync`).
In this commit we try merging batches that are already
_triggered_, but not yet _started to execute_. This way we can still
query batches for execution after the provided delay while also allowing
multiple formed batches to execute faster.

In previous implementation of `neofs-node` app object session was not
checked for substitution of the object related to it. Also, for access
checks, the session object was substituted instead of the one from the
request. This, on the one hand, made it possible to inherit the session
from the parent object for authorization for certain actions. On the
other hand, it covered the mentioned object substitution, which is a
critical vulnerability.

- check if object session relates to the requested object
- use requested object in access checks.

Re-configuration of Blobovnicza's object size limit must not affect
already stored objects. In previous implementation `Blobovnicza` didn't

re-configuration. For example, lets consider 1st configuration with 64KB
size limit for stored objects. Lets assume that we stored object of 64KB
size, and re-configured `Blobovnicza` with 32KB limit. After reboot
object should be still available, but actually it isn't. This is caused
by `Get` operation algorithm which iterates over configured size ranges
only, and doesn't process any other existing size bucket. By the way,
increasing of the object size limit didn't lead to the problem even in
previous implementation.
