helper output in logs

[Alfredo Rezinovsky <alfrenovsky@xxxxxxxxx>]

I'm using store_id_program and I want my program to ouput a Key/Value 
pair so the value goes in the logs

I tried with "log" and "tag" keys and using "%[et" and "%[ea" in 
LogFormat but it didn't worked.

There's a generic Key/Value handling or each helper needs a special 
support ?
