fix: correct configuration to activate federation attributemapper

We can't just decorate the FederatedPreauthenticatedUserDetailsAttributesMapper with @Component, because the package edu.wisc.uwss.preauth isn't @ComponentScan'ned (edu.wisc.uwss.configuration.preauth is, by design).

Corrected the logger for the Federated attributesmapper, it was incorrectly using the Default implementation (so you couldn't tell which class was lgogging).

Added a Maven profile to help test: combined-simulate-federation.
