* Remove the RequestId from DefaultConnectionContext
- Added a GetHttpContext() extension method on ConnectionContext
- Also fixed an issue not setting LastSeenUtc
* Split http and non-http layers
- This change introduces Microsoft.AspNetCore.SignalR.Http
and Microsoft.AspNetCore.Sockets.Http which expose extension methods
on IAppBuilder for wiring up a sockets and signalr pipeline.
