retry_util: add a |success_functor| to GenericRetry
Add a feature to GenericRetry allowing it to call a functor upon
success. This allows users of this function to create "log upon
successful retry" behavior, or other features that require knowing the
attempt # of the successful call to the retried function.
BUG=None
TEST=unit tests added
