Title: fetch: add --retry option to retry fetch once.

Sometimes there may be intermittent failures with hosts that work if immediately retried. Let's allow a single retry in this case with the `--retry` flag. This also behaves nicely with the `--force` flag.

@jacknagel @mistydemeo @flangy @asparagui Thoughts?
