Summary

AMQPConnection used in RabbitMQ check has been removed in php-amqplib v3: php-amqplib/php-amqplib#897 so I added support for it.

Any chance of getting this released? php-amqplib 3.0 is required for using PHP 8

@REBELinBLUE you can fork this PR or use the forked version in composer.json until this is not resolved:

"repositories": [
        {
            "type": "vcs",
            "url":  "https://github.com/sbacelic/laminas-diagnostics"
        }
    ],
  ...
  "laminas/laminas-diagnostics": "1.9.x-dev"

[REBELinBLUE]

for now I have added the following file

<?php

declare(strict_types=1);

namespace PhpAmqpLib\Connection;

// FIXME: Remove this once https://github.com/laminas/laminas-diagnostics/pull/22 has been released and
// https://github.com/liip/LiipMonitorBundle has been updated
class AMQPConnection extends AMQPStreamConnection
{
}

to my code and added it to the autoloader classmap, because it would still require LiipMonitorBundle to be updated to use the new version of this library.
