Today we save only text in wok-req.log file, in json-friendly format. 
That file is the source for any request to /logs API.

Today the translation is done at the moment of logging. So the above is 
a design change for the functionality because, in order to translate the 
message when /logs API is called, we need to save and recover the data 
differently.

I'm OK with it.

It will need further investigation, but one idea is to log the result of 
the task as well, and change the logging of requests that originate 
tasks to something like "task created for...".


Considering all the above, I think this patch can be commited as is and 
then we work on the redesign, since they are not conflicting to each other.
