Better visibility on transport errors (#278)
__Motivation__ We want to surface the close reason from `NettyConnection` in the exception returned from the request. By exposing that, we also enable users to observe transport errors and drive connection state metrics using a `HttpConnectionFilterFactory`. We should also consider elaborating the message of the `ClosedChannelException` produced by `CloseHandler.CloseEvent` __Modifications__ - expose transport level exception on `ConnectionContext` - move `SingleProcessor` from `internal` to `api` __Result__ Users have access to transport level `Exception` information to help diagnose failures and drive metrics
