hawtio-quarkus doesn't work with OpenID Connect

[grgrzybek]

@jsolovjo found that adding hawtio-oidc.properties to tests/quarkus/src/main/resources doesn't work.

I checked and while this is fine:

io.hawt.quarkus.auth.HawtioQuarkusAuthenticator#authenticate() is not using JAAS at all and there's simply io.quarkus.security.credential.PasswordCredential instance created for incoming Bearer token...

This is something to investigate a bit (not that much) later...
