The description of service bus support is incorrect in the readme file

[gcheng]

Dev estimate : 0
Test estimate : 0

Currently, it is :
Service Bus
Use either the Queue or Topic/Subscription Model

Queue and Topic/Subscription are not either/or relationship. They do not have exclusive relationship.

The right way to say is to list the functionality of Service Bus API that we are supporting, for example,

1. Create, Delete, Upgrade and Retrieve Queues.
2. Create, Delete, Upgrade and Retrieve Topics.
3. xxxxxx

It has already been fixed in the latest version of readme file. close due to duplication.
