In case node is down or failing for some reason, we can expect `Dial` to
fail. In case we actively try to replicate and `Dial` always takes 2
seconds, replication-related channels quickly become full. That affects
latency of all other write operations.

Before this commit the replication channel was quickly filled under
heavy load. This lead to the continuously increasing latency for all
write operations. Now it looks better.

Also fix a bug with replicator using the multiaddress instead of
<host>:<port> format expected by gRPC library.

Allocate memory only if a node chosen as the forwarded request receiver
has responded with a successful status.
Signed-off-by: Pavel Karpy <carpawell@nspcc.ru>
After fixing version fields in forwarded requests, a node does not check
statuses since errors are not covered by direct call error checks.

Error checkers now support wrapped errors so there is no need to
explicitly unwrap errors in `Policer`.

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.

`auditor` does not need to request SG: processor will fetch that info before
audit context initialization.
Signed-off-by: Pavel Karpy <carpawell@nspcc.ru>
That allows using `ClientCache` for storage group searching before task
context is initialized. Also, that makes it more general purpose.

After recent changes in NeoFS SDK Go library session tokens aren't
embedded into `container.Container` and `eacl.Table` structures.
Group value, session token and signature in a structure for container
and eACL.

Cache object that are being processed. That prevents concurrent
object handling when there is a few number of objects and object handling
takes more time that the policer needs for starting that object handling one
more time.

If placement contains two vectors with intersecting nodes it was possible to
send the object to the nodes twice.
Also optimizes requests: do not ask about storing the object twice from the
same node.

The node does not support asynchronous object replication anymore, so it
does not need to have replicator worker, channel and `AddTask` function.

In case we have lots of objects in a single container,
`GetContainerNodes` invoked indirectly by a policer can be seen in
pprof.

Node shouldn't perform eACL verification during GET/HEAD request
processing until full object header is received. Otherwise, for some
eACL tables request may be falsely rejected.
Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
Scenario:
* HEAD request of some object
* 1st eACL record allows op for objects with specific user attribute
* 2nd eACL record forbids op by object ID
* node doesn't store the requested object locally
With this scenario node shouldn't deny request.

It is redundant to process object headers in responses w/o object field
since result will be the same.

Request processing should not be interrupted in case of local storage
failure since error case in normal for relay nodes.
Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
ACL service should not deny request on local storage failure since in
this case relay nodes won't be able to continue the operation.

`log.With` is suitable during initialization, but in other places it induces
some overhead, even when branches with logging are not taken.
