Indexing with basic auth

[andreas-andersson]

Problem:
It's common practice to keep a staging or test server for a project and those are sometimes protected by Basic Auth.
Currently there is no way to index sites which has basic auth because there is no way of passing settings to the \GuzzleHttp\Client in ElementIndexerService ->getElementIndexableContent()

I have not found a way to work around this. Is there another way?

Suggestion:
Add a config option for the \GuzzleHttp\Client

config.php || ./config/elasticsearch.php

return [
    'httpClientOptions' => [
        'connection_timeout' => 10,
        'auth' => ['username', 'password']
    ]
]

/src/services/ElementIndexerService.php

protected function getElementIndexableContent(Element $element)
    {
        // ...
        $options = ElasticsearchPlugin::getInstance()->getSettings()->httpClientOptions;
        $client = new \GuzzleHttp\Client($options);
        // ...

/src/models/SettingsModel.php

class SettingsModel extends Model
{
    // ...
    /** @var array GuzzleHttp\Client options */
    public $httpClientOptions = [];
    // ...
