There is a need to prevent limitless abuse of MAINTENANCE status of the
storage nodes. To do this, configuration of the NeoFS network is going
to be extended with the flag which allows the state. Until this is done,
it makes sense to prepare a site for this in the code.
Define `state.NetworkSettings` interface as an abstraction of global
network configuration within the `state` package. Make
`NetMapCandidateValidator` to depend on `NetworkSettings` and provide
corresponding field setter. Change `VerifyAndUpdate` method's behavior
to return an error for candidates with MAINTENANCE state if this state
is disallowed by the network configuration. Provide `NetworkSettings`
from the wrapper over Netmap contract's client on Inner Ring application
side. The provider is implemented to statically disallow MAINTENANCE
mode in order to save previous behavior.

In previous implementation Inner Ring allowed storage nodes with any
state to register in the network. According to the current design, only
nodes with ONLINE state are allowed to enter the network map.
Create new `state` sub-package of `nodevalidation` package of Inner Ring
application. Define `state.NetMapCandidateValidator` type and provide
`NodeValidator` interface required by the Inner Ring's processor of
`Netmap` contract's notification events. Embed new validator into the
one used by the Inner Ring application.
From now all `AddPeer` notifications with node state other than `ONLINE`
will be denied.

It is useless process since subnet owner is able to delete subnet without an

removal:
1. Update nodes' attributes if they were included in the deleted subnet;
2. Remove nodes without any subnet entrance.

Alphabet nodes in notary enabled environment cannot call `UpdateState`
method to remove unwanted storage nodes from the network map,
because this method checks witness of the storage node.
To force storage node state update, alphabet nodes should invoke
new method `UpdateStateIR` which is similar to `AddPeerIR`.
State update initiated by the storage node itself is processed
the same way as before -- alphabet nods resign such transaction.

`Register` was renamed to `AddPeerIR` for consistency with
`UpdateState` changes in
https://github.com/nspcc-dev/neofs-contract/pull/227
This is protocol breaking change for notary enabled environment.
Luckily, there is no notary enabled environments anywhere except
of neofs-dev-env, so we can do such thing. We should avoid such
changes in the future, though.

In previous implementation IR incorrectly verified `SetEACL` event of
`Container` contract. The incorrect behavior could be reproduced in two
ways:
1. Create container using session, and perform `SetEACL` operation
with a key that is different from the session one.
2. Create container using session, and perform `SetEACL` w/o a
session, but sign it using session key from the `Put` operation.
The problem was in the `checkSetEACL` validation method of IR container
processor. It always used session token used for container creation
during session ownership check.

It is much more convenient to skip source creation.
Also fix some bugs:
1. `cryptoSource.Int63()` now returns number in [0, 1<<63) as required
by `rand.Source` interface.
2. Replace `cryptoSource.Uint63()` with `cryptoSource.Uint64` to allow
generate uint64 numbers directly (see rand.Source64 docs).

The client needs of the IR application are very limited and rarely change.
Interface changes of the client library should not affect the operation of
various application packages, if they do not change their requirements for
the provided functionality. To localize the use of the base client and
facilitate further support, an auxiliary package is implemented that will
only be used by the IR application.

Add name and zone arguments to `Put` method of wrapper over the Container
contract client. Pass result of `container.GetNativeNameWithZone` function
to the method in `Put` helper function. Due to this, the storage node will

There is a need to work with a set of Neo RPC nodes in order not to depend
on the failure of some nodes while others are active.
Support "multi-client" mode of morph `Client` entity. If instance is not
"multi-client", it works as before. Constructor `New` creates multi-client,
and each method performs iterating over the fixed set of endpoints until
success. Opened client connections are cached (without eviction for now).
Storage (as earlier) and IR (from now) nodes can be configured with multiple
Neo endpoints. As above, `New` creates multi-client instance, so we don't
need initialization changes on app-side.
`Wait` and `GetDesignateHash` methods of `Client` return an error from now
to detect connection errors. `NotaryEnabled` method is removed as unused.
