Support for ElasticSearch Count API

[N3m1s]

I see that your bundle does not support ES count API.

@N3m1s, maybe it can be simulated like this?

$search->setSearchType('count');
$results = $repository->execute($search, Repository::RESULTS_RAW);

@tautrimas, thanks. But since official elastic search library does have a call to count API, I think it would be a more clearer approach to add this to your Repository class.

Yes yes, this is a workaround (:
