This PR does not change anything on the outside API merely improves several aspects of our internal request handling:
Memory handling unit tests
We've added unit tests for the stream handling of all codepaths to ensure that response streams are closed and depending on the code path only read once, or if an intermediary memory stream is created to ensure that one is disposed as well. The latter is needed e.g when you want to expose the raw result on your response object.
We didn't uncover any mishaps (whoohoo) but these tests gave us the confidence to refactor other parts of our transport layer. Other aspects (responses, exceptions, errors, failover, loadbalancing) were already heavily unit tested.
Refactor transport.cs
Still a work in progress but this PR moves the request handling out of the god like Transport class into their own RequestHandler and RequestHandlerAsync classes. This improves legibility and frees transport to having one sole job and that is to coordinate requests with connectionpools.
401 handling
We've improved the way we handle 401 (Unauthorized) responses so that they do not failover and fail as fast as possible e.g a ping/sniff/call returning a 401 on a node should fail right then and there.
