Hi, Doug,

We(Mistral team) have a need to log more resources at the same time, I
am thinking about how to solve it with oslo.log module without
duplicate effort, let me explain:

In Mistral, there will be a workflow, consists of many tasks in it,
when the workflow is executed, we need to track the workflow and all
its tasks status in logs. So, we need to print workflow-id and task-id
in one line of log, e.g.

2015-06-26 04:09:50.326 19492 INFO
[c7635974-f57f-4761-a270-138ee241qefd] Task 'my_task' status change

the first is workflow-id, the other is task-id.

So, Doug, any suggestion?
