Support for service bus and for  external configs

- Service Bus should address communication between spun-up processes
and servers so we should be able to function behind a single website URL
- service bus info now held in config file on disk or in azure web app
settings (or `azure site appsetting list cheerapp`)
ignore config files
Stubbing for possible future functionality
