title: How to pass context between asynchronous method calls in Python 3.5?
body: <p>How can I pass context from on asynchronous method call to another one - without using method parameters?</p>
  
  <p>I need the feature to enrich log messages with a kind of flow ID so that I can easily trace all log messages of a specific call method flow.</p>
  
  <p>I use Python's async and await keywords (Python 3.5.x).</p>
