Resolver: cancelable resend timer event.
It is safe because re-sending still works during graceful shutdown as
long as resolving takes place (and resolve tasks set their own timeouts
that are not cancelable).
Also, the new ctx->cancelable flag can be set to make resolve task's
timeout event cancelable.
