> The current creation of {{NetworkEnvironment}} is relying on {{IOManager}} from {{TaskManagerServices}}. In order not to rely on external specific components for implementing shuffle environment, and let the specific implementation creates internal components if required.
> The current abstract {{IOManager}} has two roles, one is for file channel management based on temp directories configuration, and the other is providing abstract methods for reading/writing files. We could further extract the file channel management as a separate internal class which could be reused for all the required components, like current {{BoundedBlockingSubpartition}}. To do so, the shuffle environment should also creates its internal channel manager to break dependency with {{IOManager}}.
