inlinestyle worker list can't be read on publish

[npeltier]

cc @auniverseaway having workers on the component is not necessarily a good idea as a visitor does not have read access there :-/

• either we read it with a dedicated service,
• either we move the workers / components list to some conf node

will go for CACONFIg, it's even better imo as we get more flexibility
