lib: exponential backoff in request retry
Current sheepdog resend a request after timeout immediately. It isn't
good for avoiding high load spikes: requests that come in a short time
interval will be resent at the almost same time. This commit adds a
mechanism of exponential backoff [1] for distributing the retry
pressure.
