@leocavalcante do not merge this yet, I'll replace the tests using php-amqp/php-amqp with a library instead :)

@leocavalcante I can't figure out why the tests are failing..they all pass when I run locally, could you advise please?

[leocavalcante]

    Problem 1
      - php-amqplib/php-amqplib is locked to version v3.6.1 and an update of this package was not requested.
      - php-amqplib/php-amqplib v3.6.1 requires ext-sockets * -> it is missing from your system. Install or enable PHP's sockets extension.

I'll be adding it to the phpctl dev container variant.

There we go: opencodeco/phpctl@ee2ff47
Feel free to merge it when you think it is ready, @flavioheleno :)
