Amqp-helper

------
* :code:`AMQPService.serve()` had a 'memory leak'. Now it does not Recreate :code:`Queues` instead it redeclares the old ones.

------
* :code:`AMQPFunction` Exception handlers now get the Exception which occured passed as keyword argument :code:`exc`

------
* :code:`AMQPService` should now no longer crash if an :code:`AMQPFunction` Exception is not catched.
* :code:`AMQPFunction` Excpetion Handlers now use isinstance instead of an exact class match
* :code:`Exception` should now catch all Exceptions
* NOTE: The priority of handling is the same order as the handlers were added. That means if you added an handler for :code:`Exception` first it will catch all errors.

------
* added :code:`AMQPFunction`
* a wrapper around a function
* Exception handlers can be attached to it
* should be used in conjunction with the :code:`AMQPService`
* added :code:`AMQPService`
* a class for creating AMQP Services
* allows calling functions over amqp with a seperate queue for each function
* added :code:`AMQPClient`
* a simple rpc client inspired by the tutorial from the aio_pika documentation

Mind that the new Features are still WIP!

------
* bugfix -> regression fixed readded log_ prefix

------
* bugfix for ssl_options since it was not defined
