Validate if the endpoint has permissions to receive and send messages

[timbussmann]

The transport should check at initialization/startup time if all permissions that are required are configured correctly to be able to receive and send messages.

This seems to be blocked by missing service capabilities, see the feature request Azure/azure-service-bus-dotnet#520

The linked issue points to an archived repo, we should be checking if the new SDK allows this.

It still doesn’t.
