Adds configurable authentication converter for resource-servers with
token introspection (something very similar to what
JwtAuthenticationConverter does for resource-servers with JWT decoder).
The new (Reactive)OpaqueTokenAuthenticationConverter is given
responsibility for converting successful token introspection result
into an Authentication instance (which is currently done by a private
methods of OpaqueTokenAuthenticationProvider and
OpaqueTokenReactiveAuthenticationManager).
The default (Reactive)OpaqueTokenAuthenticationConverter, behave the
same as current private convert(OAuth2AuthenticatedPrincipal principal,
String token) methods: map authorities from scope attribute and build a
BearerTokenAuthentication.

Before, Spring Security's @Enable* annotations were meta-annotated with @Configuration.
While convenient, this is not consistent with the rest of the Spring projects and most notably
Spring Framework's @Enable annotations. Additionally, the introduction of support for
@Configuration(proxyBeanMethods=false) in Spring Framework provides a compelling reason to
remove @Configuration meta-annotation from Spring Security's @Enable annotations and allow
users to opt into their preferred configuration mode.
