Refactor props in Registry#build_features

The `props` parameter in `Registry#build_features` should to other place to avoid job-specific global properties affecting feature descriptors saved in Registry.

Start at the Registry#build_features entry point and inspect how its props parameter affects feature descriptors saved in Registry. Determine where those properties should be handled so job-specific global properties no longer affect saved descriptors. Done means the props handling has been moved to a suitable place without that cross-job effect.
