Asking for comments on this approach
The idea here is to simplify how we are passing the request the metadata type header "X-Flow-Id" to web service client methods which in turn propagate it to the other microservices that they are calling for flow tracking purposes.
Instead of passing e.g. an extra request-ctx parameter to the web service client method:
(defn entities [component entity-id request-ctx] ...)
we can include the flow-id as a stuartsierra/component dependency
