[#946] ir: Refactor usage of NeoFS API client

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.
