'Refresh' behavior

[andrii-pukhalevych]

Currently, 'refresh'=>true option for save() and saveMany() causing additional elastic query $esIndex->refresh().

I see that it is possible to pass refresh parameter in primary request:
https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html#bulk-refresh
https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update.html#docs-update-api-query-params

Should not we remove $esIndex->refresh() in favor of passing 'refresh'=>true in primary request?

[andrii-pukhalevych]

public function saveMany($entities, $options = [])
....
	$requestParams = [];
	if ($options['refresh']) {
		$requestParams['refresh'] = 'wait_for';
	}

	$esIndex = $this->getConnection()->getIndex($this->getName());
	$esIndex->addDocuments($documents, $requestParams);

And remove below:

if ($options['refresh']) {
	$esIndex->refresh();
}

Makes sense to me. I don't think the refresh option existed when saving was first implemented, but now that it exists we should use it.
