Justin Cohen 92f6c21242 Retry UploadReport on http upload failures. 
This implements a per-report retry rate limit (as opposed to per upload
rate limit in ShouldRateLimitUpload). When a report upload ends in a
retry state, an in-memory only timestamp is stored with the next
possible retry time. This timestamp is a backoff from the main thread
work interval, doubling on each attemt. Because this is only stored in
memory, on restart reports in the retry state will always be tried
once, and then fall back into the next backoff. This continues until
5 retry attempts are reached.
