This change makes the handling of graceful shutdown work for more than just http scenarios. This should allow us to move TLS further out and should also allow us to start moving things to connection middleware instead of connection adapters.
Summary of the things changed/added:
- Added IConnectionLifetimeNotificationFeature that represents an attempt to gracefully close the connection that isn't being aborted. This feels pretty awful but we may have to do it.
- Moved connection management to the ConnectionDispatcher and out of the HttpConnectionMiddleware
- Removed Http from the names of the ConnectionManager and Heartbeat
- Include hosting logs in some tests that where previously missing them
- Prevent duplicate logs from Mock CallBase an CompositeKestrelTrace
- Log ports used by transport functional tests
- Add file logging to HTTP/2 "unit" tests
This moves source code that used to be in aspnet/Common. It was only used here, so this simplifies the process of working with these internal-only APIs.

* Decouple connection objects from the server (#2535)
- Making progress towards being able to use the connection objects on the client side.
* Wait for input writer to complete before calling OnConnectionClosed (#2566)
* Wait for the ConnectionClosed token to stop tracking connections (#2574)
- The prior strategy of waiting for the pipe completed callbacks doesn't work
because blocks are returned to the memory pool after the callbacks are fired.
* Consistently handle connection resets (#2547)
* Provide better connection abort exceptions and logs
* void IConnectionDispatcher.OnConnection
- The prior strategy of waiting for the pipe completed callbacks doesn't work
because blocks are returned to the memory pool after the callbacks are fired.
- This normalizes the behavior for kestrel no matter what memory pool implementation is used. The transports should behave the same (ask for 1/2 full blocks) across pool implementations.
- Declare the minimum segment size in KestrelMemoryPool
- Updated the AdaptedPipeline to use MinimumSegmentSize / 2
- Made TransportConnecton derive from ConnectionContext
- Less objects, less opinions about what the ConnectionContext is. This diverges from what we do with HttpContext but it seems better overall.
- Made DefaultConnectionContext
- Usable for unit testing
- Usable for benchmarking
* Renames from API review
- Rename Microsoft.AspNetCore.Protocols.Abstractions to Microsoft.AspNetCore.Connections.Abstractions.
- Renamed IConnectionHandler to IConnectionDispatcher (and related properties and types)
- Added ConnectionHandler and UseConnectionHandler extension method to Connections.Abstractions.
- Use ActivatorUtilties to create the ConnectionHandler
* Metadata is now a first class property on ConnectionContext
- Make IConnectionMetadata a manatory top level feature on ConnectionContext
- TransportConnection will lazily manifest ConnectionMetadata on first access.
This should avoid allocations since Kestrel isn't using this today.
- This change aims to clean up the feature interfaces
used by kestrel and exposed by protocol absractions. It splits out the
IConnectionTransportFeature into smaller features that may or may
not be implemented on the connection.
- Added all of the features from Socket.Abstractions
in an attempt to make it go away completely. As a result
the helper methods and extensions have all been added here.
- Change IConnectionHandler to take TransportConnection. This cleans up the interface and makes it more explicit what features are required by Kestrel

- Use the pipe events and removed the Tasks from ConnectionContext
- Remove OnConnectionClosed from FrameConnection. Since the `FrameConnetion` is a single middleware, not the entire pipeline, we shouldn't need to wait on the connection close there.
- It seems like the callbacks are rooted on the pipe even after they fire. This needs to be investigated in pipelines.
* Added initial connection middleware pipeline
- Implemented IConnectionBuilder on ListenOptions. Kept IConnectionAdapter for now.
- Delay the configure callback for ListenOptions until the server has started.
- Added ConnectionLimitMiddleware and HttpConnectionMiddleware
- Expose ConnectionAborted and ConnectionClosed on ConnectionContext and
IConnectionTransportFeature
- Updated the tests
- Removed IConnectionApplicationFeature
- Moved Application to IConnectionTransportFeature
PackageLineup is a way to manage PackageReference versions across large projects. It removes the version information from the repository and instead pulls the information from an external "lineup" file.
- Added Protocols.Abstractions
- IConnectionHandler.OnConnection takes an IFeatureCollection instead of
IConnectionInfo
- Removed IConnectionContext and IConnectionInformation replaced with
IConnectionTransportFeature
- Updated FrameConnectionContext and FrameContext to have the relevant
state instead of flowing the ConnectionInformation.
- Updated tests
