Jwt DSL Configuration should accept an AuthenticationManager

[jzheaux]

In Reactive Resource Server, one can switch out the JWT authentication manager:

http
    .oauth2ResourceServer()
        .jwt()
            .authenticationManager(...)

It'd be nice to have this same feature on the Servlet side. This AuthenticationManager would be used by the BearerTokenAuthenticationFilter instead of any shared one.

Actually, in this case, I nearly have a PR ready myself, I just failed to mark it in progress. Thanks for checking, though, @clevertension!
