"Unsupported version" error using neofs-cli v0.21.1 with recent dev-env

Setup

dev-env 74717177c088b0833161a4a0bb2067412a69a18c, neofs-cli v0.21.1:

$ ~/bin/neofs-cli container get -r 192.168.130.73:8080 --cid 5LSSzNunga4kN2Q5yAPnACaSN3HjzkVVgbVGT3hXeLNE -k KxDgvEKzgSBPPfuVfw67oPQBSjidEiqTHURKSDL1R7yGaGYAeYnr
Error: rpc error: unsupported version 2.8

Expected Behavior

Container data returned successfully.

It works with neofs-cli v0.22.0.

[alexvanin]

This is expected when latest neofs-cli v0.22.0 (with API v2.8) connects to neofs-node v0.21.1 (with API v2.7). Client does not support auto negotiation yet, but it definitely will.

However it is not expected for neofs-cli v0.21.1 to throw such error when connecting to neofs-node v0.21.1 or later.

[cthulhu-rider]

The problem is caused by the fact that API client returns an error if container version is newer than corresponding API Go library version. It is checked here.
