Is there a way to configure spring-security-config's permitAll behavior?

[dzharikhin]

spring-security-config have option permitAll - it tries to auth request if auth is provided, but if not - execution is still allowed
spring-security-config does not use org.springframework.security.access.intercept.AbstractSecurityInterceptor in any way
but the behavior is useful to migrate api from REST to gRPC

It can be achieved via some tweaks in code of the SecurityInterceptor, but before I create PR I wan't to make sure I'm not missing a way to configure such behavior without code changes
