多租户，其实是在用户这层之上，抽象出了一层account。

账户和账户之间，资源都是隔离的，同时，账户和账户之间也可以通过export或者import来共享一些这个主题的消息。

使用场景：在一个企业内，只部署了一套nats服务，但是有很多个应用都需要使用这套nats服务，但是应用和应用之间的这个消息相互之间是完全隔离的，那这就能用到这种多租户的架构。

多租户配置详解：

Streams are messages your application publishes. Importing applications won’t be able to make requests from your applications but will be able to consume messages you generate.
Services are messages your application can consume and act on, enabling other accounts to make requests that are fulfilled by your account.

accounts: {
    A: {
        users: [
            {user: a, password: a}
        ]
        exports: [
            {stream: puba.>}
            {service: pubq.>}
            {stream: b.>, accounts: [B]}
            {service: q.b, accounts: [B]}
        ]
    },
    B: {
        users: [
            {nkey: UXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX}
        ]
        imports: [
            {stream: {account: A, subject: b.>}}
            {service: {account: A, subject: q.b}}
        ]
    },
    C: {
        users: [
            {user: c, password: c}
        ]
        imports: [
            {stream: {account: A, subject: puba.>}, prefix: from_a}
            {service: {account: A, subject: pubq.C}, to: Q}
        ]
    },
}
