In previous implementation node always sent bootstrap requests with
"online" network state. This provoked switching to online of the nodes
under maintenance.

In the 2nd version, there was a database format change: buckets have changed
their keys, so it becomes impossible to check the version in the 1 -> 2+
migrations because of different buckets that store info about the version.

Storage node should not provide NeoFS Object API service when it is
under maintenance.
Declare `Common` service that unifies behavior of all object operations.
The implementation pre-checks if node is under maintenance and returns
`apistatus.NodeUnderMaintenance` if so. Use `Common` service as a first
logical processor in object service pipeline.

In some scenarios original session can be unrelated to the objects which
are read internally by the node. For example, node requests child
objects when removing the parent one.
Tune internal NeoFS API client used by node's Object API server to
ignore unrelated sessions in `GetObject` / `HeadObject` / `PayloadRange`
ops.

If shard ID is stored in metabase (it is not the first time boot), read it,
set it, use it (not a generated one) in the metrics writer.

Make it store its internal `zap.Logger`'s level. Also, make all the
components to accept internal `logger.Logger` instead of `zap.Logger`; it
will simplify future refactor.

Current spec allows denying GET_RANGE requests from other storage nodes.
However, GET should always be allowed and it is enough to perform
GET_RANGE locally

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.

If the contract returns a netmap that does not contain the node, update
local `NodeInfo`. It fixes `neofs-cli netmap nodeinfo` command that printed
"state: online" previously.

Node response with `NODE_UNDER_MAINTENANCE` status signals that the node
was switched to maintenance mode. There is a delay between the actual
switch and the reflection in the network map of up to one epoch. To
speed up the reaction to the maintenance, it is required to recognize
such node responses in the Policer.
Make `Policer.processNodes` to exclude elements with shortage decreasing
on `NODE_UNDER_MAINTENANCE` status response.

Nodes under maintenance SHOULD not respond to object requests. Based on
this, storage node's Policer SHOULD consider such nodes as problem ones.
However, to prevent spam with the new replicas, on the contrary, Policer
should consider them normal.
Make `Policer.processNodes` to exclude elements if `IsMaintenance()`
with shortage decreasing.

It doesn't make sense to check object relation in session check of
`ObjectService.Put` RPC which has been spawned by `ObjectService.Delete`

object to be created.

Currently, when removing shard special care must be taken with respect
to shard numbering. `mode: disabled` allows to leave shard configuration
in place while also ignoring it during initialization. This makes
disk replacement much more convenient.
