Leonard Lyubich e6b30aed36 [] object/search: Re-sign original requests during forwarding
In previous implementation node's Object Search V2 service handler created a
new request for each RPC. Now original requests are re-signed according to
API specification. Logical handler abstracts from this version-dependent
logic through `RequestForwarder` callback.
