* Make un-graceful shutdown a bit more graceful
- Change how graceful shutdown is done to ensure there are no errors on shutdown.
- Avoid closing pipes from under other components that own those pipes.
- Close the application output so that the application's read loop ends gracefully. For websockets, we cancel the token, for other transports, we close the output directly.
- Closing pipes gracefully in most cases. The only case where we forcefully close the pipes is during application shutdown
- Return 404 if sending to connection after disposal
- Added tests
- We made a change to not initialize pipes up front
on connection creation. That change make it null ref in disposal because we didn't check if the pipes were initialized.
- Added a test
- Also fixed the EchoConnectionHandler in the functional ts tests.
