[#1680] morph/netmap: Support HomomorphicHashingDisabled config

`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.
