* failing test
* failing test but needs real butterfly server running..need to fix that...also worked out ive broken tracing...yey
* brought in butterfly source code so i can work out how to write acceptance tests for this...
* fixed the bug but still need to fix tracing
* tracing working again across services but need to make tracing hook into new Ocelot middleware as it still uses asp.net middleware
* removed butterfly libs brought in for testing
* initial commits around using any id servers
* add your own id server for admin area
* lots of refactoring, now instead of injecting IWebHostBuilder we just set the Ocelot base url as a configuration extension method..this means people can pass it in on the command line aswell as hardcode which is OK I guess, also can now use your own IdentityServer to authenticate admin area
* updated docs for #231
* some tests that hopefully bump up coverage
* hacked together load balancing reroutes in fileconfig
* some renaming and refactoring
* more renames
* hacked away the old config json
