1. Definded with properties users (static) are configured using property map (no need of indexes)
2. AuthenticationProvider that authenticates them is always registered (if not needed - don't configure them)
3. UserDetailsService (in case of missing - won't be registered)
4. Spring security user (spring.security.username) will be registered together with other users (if any). If any - it will be system-wide, otherwise tenant-scoped.
5. UserPrincipal renamed to TenantAwareUser in order to match its purpose.
6. Some if its fields are removes as not needed - to be closer to spring security user
7. DefaultRolloutApprovalStrategy now use UserAuthoritiesResolver instead of UserDetailsService as the central point of truth
