Merge branch 'udsperson-constructor' into 'master'

refactor: change injection strategy for UdsPersonUserDetailsServiceImpl

`UdsPersonUserDetailsServiceImpl` is not initialized automatically by either of the primary 'local-users' or 'preauth' Profiles. It's typically constructed by downstream projects manually (not by component scanning).
    
 Registering more than 1 `UserDetailsService` - say one for the uw-spring-security stack, and a different one for `UdsPersonUserDetailsServiceImpl` - will result in ApplicationContext initialization errors as the Configuration classes provided in uw-spring-security-config expect 1 and only 1 UserDetailsService.
    
The recommended use now for `UdsPersonUserDetailsServiceImpl` is to provide the needed `UserDetailsService` by hand, not by automatic autowiring. If the 1 UserDetailsService provided by uw-spring-security is appropriate, it's easy to retrieve from the ApplicationContext; if an alternate one is required it can be constructed without registering it as a @Bean.
