Pavel Karpy 7c02a2e251 [#1087] *: Adopt SDK changes
- Update `neofs-sdk-go`:
v0.0.0-20211230072947-1fe37df88f80 => v0.0.0-20220113123743-7f3162110659

- Add client interface that duplicates SDK's client behaviour and new
`MultiAddressClient` interface that has method that iterates over wrapped
clients.

- Also start using simple client mode that does not require parsing statuses
outside the SDK library.
