In this commit we implement algorithm for CRDT trees from
https://martin.klepmann.com/papers/move-op.pdf
Each tree is identified by the ID of a container it belongs to
and the tree name itself. Essentially, it is a sequence of operations
which should be applied in chronological order to get a usual tree
representation.
There are 2 backends for now: bbolt database and in-memory.
In-memory backend is here for debugging and will eventually act
as a memory-cache for the on-disk database.

Replace `ErrRangeOutOfBounds` error from `pkg/core/object` package with
`ObjectOutOfRange` from `apistatus` package. That error is returned by
storage node's server as NeoFS API statuses.

Shard is intended to be used as a separate failure domain,
which usually resides on a separate disk. Thus, sequential
initialization is bound by IO and this change speeds up thing a bit.

Do not calculate and do not write homomorphic hash for containers that were
configured to store objects without hash.

Do not use homomorphic hash in storage group for containers that have
`homomorphic_hashing_disabled` set to `true`.

If the container ID is not nil and not equal to the container ID in the
request, consider bearer token invalid.

Allocate memory only if a node chosen as the forwarded request receiver
has responded with a successful status.

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.

That allows using `ClientCache` for storage group searching before task
context is initialized. Also, that makes it more general purpose.

Do not use `Marshal()` with object's payload. Use `ReadFromObject` func from
SDK instead. That allows checking both attributes and SG body's expiration
epoch.

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.
