Authenticated annotation is not supported for the reactive routes

[sberyozkin]

Description
@Authenticated is meant to resolve the problems similar to the one at #4544 where an access to the resource has to be denied by simply requiring that a user must've been authenticated.

Implementation ideas
Stuart @stuartwdouglas recommends that CDI interceptor has to be created to support @Authenticated on the reactive routes.
@michalszynkiewicz FYI, given that you are already working on the CDI security interceptors :-)

it's almost there: https://github.com/quarkusio/quarkus/pull/4413/files#diff-2e5dbf19cb91f299787caf7fac571c08R1 ;)
I think a dedicated handler to translate the exception to a proper status code would be required. But it should be easy to implement it (I already played with it but it didn't work for Resteasy on servlet so went back to exception mappers).

Should we target it in 1.0 or can it be done later? If it's for 1.0 I'll try to make it work in my current PR.
