With non-blocking pool restricted by 10 in capacity, the probability of
dropping events is unexpectedly big. Notifications are an essential part of the FrostFS,
we should not drop anything, especially new epochs.

It led to a neo-go dead-lock in the `subscriber` component. Subscribing to
notifications is the same RPC as any others, so it could also be blocked
forever if no async listening (reading the notification channel) routine
exists. If a number of subscriptions is big enough (or a caller is lucky
enough) subscribing loop might have not finished subscribing before the
first notification is received and then: subscribing RPC is blocked by
received notification (non)handling and listening notifications routine is
blocked by not finished subscription loop.
That commit starts listening notification channel _before_ any subscription
actions.

We have already had and solved plenty of deposit issues and notary balance
is a really important thing. Deserves to be INFO even before the huge logs
severity refactor, happens on an app start only.

It does not use deprecated methods anymore but also adds more code that
removes. Future refactor that will affect more components will optimize
usage of the updated API.

Could be related to "websocket users limit reached" on the `neo-go` server
side when an SN/IR is rebooting repeatedly.

1. Replace `mn` function with a `sigCount`.
2. Use `notary.FakeMultisigAccount` for account creation.

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.

After recent Netmap contract changes all read methods which return
network map (either candidates or snapshots) encode node descriptors
into same structure.
Decode `netmap.Node` contract-side structure from the call results.
Replace node state with the value from the `netmap.Node.State` field.

After recent changes Netmap contract can send `UpdateState` notification
event with `MAINTENANCE` node's state. There is a need to provide
functionality to work with the status.
Provide `UpdatePeer.Maintenance` method. Support new state in
`ParseUpdatePeer` and `ParseUpdatePeerNotary` functions.

After recent changes in NeoFS protocol storage nodes can be in
`MAINTENANCE` state. There is a need to support this state in
`UpdateState` operation.
Add `UpdatePeerPrm.SetMaintenance` method which makes node to be
switched into `MAINTENANCE` mode after the `UpdatePeerState` operation.
New functionality is going to be used in Storage node application for
Control API serving.
