Make Ocelot work with service fabric DNS and naming service for guest exe and stateless (#242)

Browse Source 
* test for issue

* added service fabric sample

* working!!

* changed sample naming to Ocelot

* removed files we dont need

* removed files we dont need

* updated sample gitignore

* updated sample gitignore

* getting ocelot to work with service fabric using the reverse proxy

* #238 - added support for service fabric discovery provider, proxies requests through naming service, wont work on partioned service fabric services yet

* #238 - Manually tested service fabric using sample..all seems OK. Made some changes after testing, added docs

* #238 - added docs for servic fabric
