Before, when the target RPC server was unavailable, requests made
by CLI didn't wait for a timeout specified by the `--timeout` option
if the timeout was more than 20 seconds. It's because of the gRPC
default backoff strategy. Adding this option fixes that behavior.

For `frostfs-cli` it is ok to use grpc-client without blocking,
as `frostfs-cli` will perform RPC call anyway.
