feat: new LocalUserDetailsLoader for populating local-users store
New optional user interface for populating the LocalUserDetailsManagerImpl instance provided in the local-users
profile. The default configuration will still use the existing LocalUserDetailsAttributesMapper.Default
implementation.
To switch to the new loader, set the edu.wisc.uwss.local.userDetailsLoader.enabled
Environment property to true. The default resource loaded is edu/wisc/uwss/local/local-users.json (classpath), to change that location set the edu.wisc.uwss.local.userDetailsLoader.resource
Environment property to a valid Spring Resource expression ('classpath:', 'file:', etc).
