Adding retrying behavior on ElasticSearchIO

   @aalbatross please do not squash your commits until the end of the review 
(just after LGTM) it is very difficult to follow review commits otherwise. 
Also, as an advice try to have as small commits (but still coherent) as 
possible. It simplifies the reading of your code path  at the following of 
review comments. Before the merge a sole feature commit is fine as long as it 
is the good isolation size (retry feature is).

> Currently an overloaded ES server will result in clients failing fast.
> I suggest implementing backoff pauses.  Perhaps something like this:
> {code}
>     ElasticsearchIO.ConnectionConfiguration conn = 
> ElasticsearchIO.ConnectionConfiguration
>       .create(new String[]{"http://...:9200"}, "test", "test")
>       .retryWithWaitStrategy(WaitStrategies.exponentialBackoff(1000, 
> TimeUnit.MILLISECONDS)
>       .retryWithStopStrategy(StopStrategies.stopAfterAttempt(10)
>     );
> {code}
