> Currently when client wants to publish messages to a specific topic (client 
> doesn't know which hub owns this topic), it needs to ask default server which 
> hub owns it. Client needs to connect to default server each time, even the 
> channel to default server has been established. So too many unused 
> connections will be opened and closed, when it publishes to different topics 
> concurrently.
> Reuses existed channel to default server to avoid the above issue.
