Explicit entry for ewoks config

I dont know where to talk about it si here is.

I think it would be much better to set in supervisor an explicit var for the location of the configuration.

That's what i am doing with every projects. Removing magics.

An explicit link allow anybody to follow it without doing deep inside. Surprisingly it make it explicit :-)
I think it is not negligible when your in helpdesk or oncall, that's a kind of autodocumentation
Plus, it allows, without knowledge, to change it if needed for test or what ever
