Forward detector flag autoconfiguration

As discussed in the configuration meeting we want all available detectors to be enabled all the time in reconstruction/data jobs. What this MR does is it enabled forward detectors only for data by default. AFP is the only client for now and was also migrated.

Keeping Draft for a day if there are objections.
