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.

It is much more convenient to skip source creation.
Also fix some bugs:

by `rand.Source` interface.
2. Replace `cryptoSource.Uint63()` with `cryptoSource.Uint64` to allow

In notary disabled environment, approval of container creation with nice
name attribute takes much more additional GAS than other operations
(due to NNS invocation).
Morph library changes:
* add the ability to specify per-op fees using `StaticClient` options;
* add the ability to customize fee for `Put` operation with named
container in container morph client.
Inner Ring changes:
* add `fee.named_container_register` config value which specifies
additional GAS fee for the approvals of the named container
registrations;
* pass the config value to `WithCustomFeeForNamedPut` option of
container morph client.

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.
