Service Bus samples are using outdated service bus release

The samples under [here](https://github.com/Azure/azure-libraries-for-java/tree/master/azure-samples/src/main/java/com/microsoft/azure/management/servicebus/samples) are written against release 0.9.7 of com.microsoft.azure:azure-servicebus (as shown [here](https://github.com/Azure/azure-libraries-for-java/blob/master/azure-samples/pom.xml#L51)). This release dates back to October 2016 and no longer represents how to use Service Bus using more recent releases. These samples should all be updated to use the 1.2.7, or 2.0.0-preview, release of the service bus API.
