RabbitMQ (amqp-protocol) support

[MikhailNazarov]

Thanks for the long awaited framework. You have done a great job!

I would really like to get support for the async amqp protocol, are there any plans to add it in the near future? Thank you!

I've got a draft that works (unless it crashes randomly upon hard to track down races 😉), which i expect to polish enough to PR in a week or so.

@MikhailNazarov do you have any specific features/perf requirements in mind so i can try to adjust my work accordingly?

RabbitMQ/AMQP experimental support was added, thanks to Ivan Trofimov. We'd appreciate feedback :)

Thank you very much , I will definitely test this feature when I get to this task

Hope you'll find it usefull)

Please keep in mind that although i tried pretty hard to test lots of possible scenarios i might've missed some, and since this is not yet used by anyone and implementation wasn't as straightforward as i'd like it to be some bugs might be lurking - if you encounter them please report it either here in issue (preferably) or to my dms.

There are some features that are not yet supported (dynamic-config, headers) and some are lacking (metrics, some tests), but sadly i didn't have enough free time to implement them right away. Feel free to file an issue if you need any enhancements

Looks like the support for AMPQ is fine. Closing this issue, improvements would be done in a separate issues/PRs.
