Do not use node's local storage if it is clear that an object will be
removed anyway as a redundant. It requires moving the changing local storage
logic from the validation step to the local target implementation.
It allows performing any relations checks (e.g. object locking) only if a
node is considered as a valid container member and is expected to store
(stored previously) all the helper objects (e.g. `LOCK`, `TOMBSTONE`, etc).

All logic errors are wrapped in `logicerr.Logical` type and do not

If an object has not been marked for removal by the GC in the current epoch
yet but has already expired, respond with `ErrObjectNotFound` api status.
Also, optimize shard iteration: a node must stop any iteration if the object
is found but gonna be removed soon.
All the checks are performed by the Metabase.

There is a need to generalize single-address client to group-address client.
To do this, we can re-implement `Client` interface from NeoFS API Go library
and still use it in the application code. There is a problem with method
`Raw` which must return single-address raw client. So as not to make changes
to API library we need to overload Client interface in order to support
`Raw` method in group-address client implementation.
Define `Client` interface in new `pkg/core/client` package. Completely
inherit API `Client` interface. Add `RawForAddress` method to build raw
client for the single node address. Adopt the application code that used Raw
method to work with new `Client`.
