Append a hook to be able to overwrite access log
Summary
Access are logged by using whatToTrace or customToTrace. whatToTrace and customToTrace are static values because they are computed at log in process.
The aim here is to be able to log a dynamic value that can be different depending on the virtualHost like the group or profile used by the user to match the access rule.
Design proposition
Append a hook to overwrite customToTrace by using a custom function.
