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.

After recent changes in the NeoFS API protocol network configuration
contains `MaintenanceModeAllowed` boolean flag. There is a need to
support the config value in all NeoFS applications.
Provide `Client.MaintenanceModeAllowed` method which read the config
from the Sidechain. Extend `NetworkConfiguration` structure with
`MaintenanceModeAllowed` field.

`NetworkConfiguration` represents NeoFS network configuration stored in
the Sidechain. In previous implementation the configuration missed flag
of disabled homomorphic hashing.
Add `NetworkConfiguration.HomomorphicHashingDisabled` boolean field.
Decode the field in `Client.ReadNetworkConfiguration` method. Print this
value in `netmap netinfo` command of NeoFS CLI.

`readBoolConfig` method is going to be reused for reading other
configuration values. All boolean settings are `false` by default, so it
makes sense to return default value on missing key directly from
`readBoolConfig`.
Handle `ErrConfigNotFound` case in `readBoolConfig` method. Change
`HomomorphicHashDisabled` method to call `readBoolConfig` directly.

New network status of storage nodes is going to be introduced. To
simplify the addition, it would be useful to prepare the code for this.

Sometimes it is useful to track sidechain events processed by the node.
For example, we need some easy way to look up for log messages about new
epoch notifications.
Make `subscriber.Subscriber` to log names of all events received from
the sidechain notification channel.

Some methods add "IR" suffix to its names in notary enabled envs
because of contract logic. It was broken due to incorrect notary state
reading (tryNotary != notary is enabled).

There is a need to sync container-related caching mechanism with the
actual Sidechain changes. To do this, node should be able to listen
incoming notifications about container ops.
Define `PutSuccess` / `DeleteSuccess` notification event's parsers.
Subscribe to these events in node app. As initial implementation node
will log event receipts. Later handling is going to be practically
complicated.

Handling notification in a synchronous manner may lead to a blocking state

Core changes:
* avoid package-colliding variable naming
* avoid using pointers to IDs where unnecessary
* avoid using `idSDK` import alias pattern
* use `EncodeToString` for protocol string calculation and `String` for
printing
