Log TraceIdentifier for ApplicationErrors

[halter73]

If we implemented IHttpRequestIdentifierFeature in Frame.FeatureCollection.cs, we would have access to the TraceIdentifier (Request ID) instead of just the ConnectionId. I think Kestrel should log both identifiers when possible. I think something (maybe Hosting) should log which TraceIdentifiers correspond with which ConnectionIds for every request.

Hosting should just pick up our implementation of IHttpRequestIdentifierFeature instead of adding the one from HttpAbstractions to the IFeatureCollection.

Below are the current logs from an unhandled exception fro a request with TraceIdentifier: 0HL2MNKLICAB4 and ConnectionId: 0HL2MNKLGDKRK.
