Evaluate timeout CLI parameter against block time about neofs-node HOT 1 OPEN

i think it maybe really useful when timeout defaults

with set --timeout flag, i don't think additional request justifies itself: network resources are spent only for writing a warning. IMO it would be more efficient to attach such information to the response context along with the container ID (response X-header?). However, in this case it is useful to be able to let the server know whether the client plans to process this value or not (additional request X-header?)

if await {
  req <- new(cid, "__NEOFS__ATTACH_POLL_INTEVAL")
} else {
  req <- new(cid)
}

resp <- send(req)

if await {
  interval <- get_header(resp, "__NEOFS__ATTACH_POLL_INTEVAL")
  if interval == 0 {
    interval <- 5s // some sane default recommended by the protocol
  }
  poll(cid, interval)
}

buuut these are protocol extensions
