Title: Workers will now retry (but not re-resolve) on some ExecuteFetch failures

@enisoc @alainjobart

First pass at retrying for errors. Wanted to get your thoughts on this approach - still need to add re-resolving, but I think it should be straight-forward with this approach.

Existing tests pass, but nothing is explicitly testing tablets temporarily going away. I'd like to add something to our test suite along those lines (maybe vtctl Pause/Resume commands, or maybe just easy ways for disabling and enabling queryservice).
