Add proof of async tasks with dramatic and periodiq

[falvaradorodriguez]

• Related with [Research] How to do async tasks #7

This RP is not intended to be mergable. It is therefore kept as a draft.

It is used as a proof of concept for dramatiq and periodiq in conjunction with FastAPI.

In the proof of concept the following is done:

• A queue is created simulating the queue that will contain the events of the contracts.
• Use pika to consume events from the queue and launch an asynchronous task.
• The asynchronous tasks are managed with dramatiq.
• An example of a cron task is also added, with periodiq to validate that dramatiq and celery can potentially do the same (https://dramatiq.io/motivation.html#compared-to)

It is possible to send test messages to the queue using python scripts/send_test_message_rabbitmq.py.
