"IProto features" are available since Tarantool 2.10 and there is no need to even try to fetch them for lower versions. Such check there is in netbox code [1].
Before this patch cartridge remote control closed the connection after RequestProtocolVersion however but for netbox it worked fine.
So let's uniform behaviour between connectors adding a small check to skip request if there is a gurarntee that "IProto features" are not supported.
Closes #283
