Latest version causing insane worker CPU usage about yii2-beanstalk

[udokmeci]

@adrianpaiva1 This is probably beacuse of the 'ticks' are removed. You can use it like this or can add 'sleep' to your controller.
To investigate it further can you please let me know which version of php you are using?
Thanks,

Hi I'm running PHP 7.1.71. Thanks for looking into this, love this library!

I currently have the sleep setting at 3.

Just give you some more info, none of the workers were actually processing jobs. They had crazy high CPU usage without any jobs.

Hi again,
Sleep 3 is very low i mean you can set it something like 100. It is ms. Still it should reduce CPU usage, did it?
Thank you for support.

Hi, I have the same issue since I installed the last version.

This is the unchanged config which causes high CPU load on both the PHP worker process and the beanstalk process:

'beanstalk'    => [
			'class'          => 'udokmeci\yii2beanstalk\Beanstalk',
			'host'           => '127.0.0.1',
			'port'           => 11300,
			'connectTimeout' => 1,
			'sleep'          => 60,
		],

I've changed the sleep value to 1000, but not no avail.

A different software package that uses the previous version of yii2-beanstalk uses sleep 60 to and does not show out of bound CPU usage.

It looks like the issue is pointing to getting a RESPONSE_TIMED_OUT whilst trying to reserve the tube in beforeAction of BeanstalkController.php (lines 303-320):

$job = $bean->reserve(0);
if (!$job) {
  continue;
}

Using time-out of 0 keeps the process cycling in the while loop and consuming all available CPU cycles. The after job sleep needs to be added before the continue to fix this issue.

Added pull request #37 to make CPU load manageable through sleep.

Thanks merged and released! Controller or Component could also have a default timeout for reserve method.
