This closes #2

This PR just setup the project:

• Setup poetry and dependencies (qpid-python)
• Setup python checkers: isort, flake, black, mypy
• Setup a simple temporary test which connect to the RabbitMQ amqp 1.0 server
• Setup a simple action which run a rabbitmq-server service, build the project and run the test suite (for the moment just the simple test as above)
