Both `meta` and `write-cache` are expected to have a fast underlying disk,
so it does not seem like an optimisation. Moreover, `write-cache`'s `Head`
is a `Get` with payload cutting, it _must_ use more memory for no reason
(`meta` was created for such requests). Also, `write-cache` does not allow
performing any "meta" relations checks (such as locking, tombstoning).

We use cache to avoid policing the same object multiple times in a short
time span (< 30 seconds). If we have 200_000 objects in a blobstor, it is a bit useless
-- if it takes 1 second to process an object and we have `replicator.pool_size: 20`
in config, the next iteration will happen in 10_000 second which is much
larger than 30 second. However we still consume a lot of memory, so it
makes sense to use saner default.

In NeoFS containers can be removed on behalf of its owner only. To
improve user experience, there is a need to add ownership check to the
removal command of the NeoFS CLI.
Check container ownership in `container delete` command `Run` function.
The check can be skipped by `--force` option.

Includes extending listing methods in the Storage Engine with object types.
It allows tuning replication/policer algorithms: container nodes do
not remove `LOCK` objects as redundant and try to fulfill `LOCK` placement

A container node is expected to have full "get" access to assemble the
object.
A non-container node is expected to forward any request to a container node.
Any token is expected to be issued for an original request sender not for a
node so any new request is invalid by design with that token.

Do not lose meta information of the original requests: cache session and
bearer tokens of the original request b/w a new generated ones. Middle
request wrappers should not contain any meta information, since it is
useless (e.g. ACL service checks only the original tokens).

After presenting request statuses on the API level, all the errors are
unwrapped before sending to the caller side. It led to a losing invalid

It is not an error: removing virtual object is expected and should be just
skipped. Getting a virtual object with `raw` flag is considered as an
impossible action, all the virtual objects removals will be handled via
their children's removals implicitly.

Currently there is a possibility for modifying operations to fail
because of I/O errors and a new tree to be created on another shard.
This commit adds existence check for modifying operations.
Read operations remain as they are, not to slow things.
`TreeDrop` is an exception, because this is a tree removal and trying
multiple shards is not an unwanted behaviour.

In previous implementation node lost maintenance status after successful

bootstrap requests with the "online" state instead of "maintenance".

There is a need to support NeoFS-binary sessions along with JSON ones in
NeoFS CLI.
Provide generic `common.ReadBinaryOrJSON` functions which tries to
decode NeoFS-binary structure and falls back to JSON format. Use this
function in all places with token reading.

In previous implementation turning to maintenance mode using NeoFS CLI
required NeoFS API endpoint. This was not convenient from the user
perspective. It's worth to move networks settings' check to the server
side.
Add `force_maintenance` field to `SetNetmapStatusRequest.Body` message
of Control API. Add `force` flag to `neofs-cli control set-status`
command which sets corresponding field in the requests body if status is
`maintenance`. Force flag is ignored for any other status.

In previous implementation `ObjectService.Get` RPC handler failed with
`parent address in child object differs` while assembling the "big"
object. This was caused by the child check which required parent
reference to be set in all child objects. The check was impracticable
because not all elements of the split-chain have a link to the parent.
Make `execCtx.isChild` to return `true` if parameterized object has no
parent header in its own header.

It does not make sense to open remote sessions with the storage node in
`get`, `head`, `search`, `range` and `hash` sub-commands of `neofs-cli
object` command.
Do not use NeoFS API `SessionService` in mentioned commands. Decode
object session from JSON file specified `--session` flag. Perform some
sanity checks instantly on CLI side.
