Below example shows starting the server without/with accounts.
Then subscribing on ">"
followed by querying /subsz.
When started with accounts the subscription does not appear.
(I tried /connz etc.. these worked. /connz?subs=1 worked as expected)

With accounts:

> cat X_BAD.cfg
listen: localhost:4222
http: localhost:8000
accounts: {
    USERS {
        users: [
            {user: "user", password: "pwd"}
        ]
    },
}

IIRC subs may only do global account. Needs to be part of our update to monitoring to be more account aware. Need to spec out what we want and impl.
