Implement NeoFS ID contact's client which is responsible for collecting call
arguments and parsing stack items. Initially only key listing method is
supported.

To enable notary support in main chain, notary subsystem should not get
alphabet keys from (main chain) committee. This key fetcher is now
separated and may be overwritten by `WithAlphabetSource` option.

Neo node can return integers values where []byte is expected.
To cover such cases, try to parse integers in `BytesFromStackItem`.

New neo-go version provides:
- new type for roles in `RoleManagement` contract,
- methods to get keys from `RoleManagement` contract,
- new way to sign notary transaction.

RoleManagement native contract (ex designate contract) stores list
of keys per role. Main net uses NeoFSAlphabet role to store keys of
alphabet nodes of inner ring. Side chain uses the same role to store
keys of all inner ring nodes, including alphabet.

Implement API methods of the Container contracts client corresponding
to the calls of the contract for storing the used space of the container
("putContainerSize", "getContainerSize", "listContainerSizes"). Extend
the wrapper over the client with methods abstracted from sidechen calls.
In particular, the method of storing the value will be used to record
the estimates of the used space of containers calculated by the network
participants.

NeoFS contract produces event with three arguments:

In #37 we've decided to remove length check, because smart contract would
fail on casting `nil` value from storage to `[]byte` producing FAULT state.
Apparently it does not fail, so we have to check length explicitly.
