[FEATURE] Add stream_context option to WebOpcacheResetExecuteTask

[sabbelasichon]

• This is useful for example to execute the task if we have to provide Basic Authentication

[helhum]

can you please call that stream_context

[sabbelasichon]

Sure. Only the option? Or the variable too?

I have fixed it. Hope everything is fine now.

[simonschaufi]

You can now just pass the option stream_context to the task TYPO3\Surf\Task\Php\WebOpcacheResetExecuteTask:

$workflow->setTaskOptions('TYPO3\\Surf\\Task\\Php\\WebOpcacheResetExecuteTask',array(
        'baseUrl' => $baseUrl,
        'stream_context' => array(
            'http' => array(
                'header' => 'Authorization: Basic '.base64_encode("username:password"),
            ),
        ),
    ));
