Fixes: #1657
cio.Creatorinterface to start logging binary as per https://github.com/containerd/containerd/blob/main/cmd/containerd-shim-runc-v2/process/io.go#L247 which creates 2 pipes to forward container output to the logging binary and one pipe to check if the logging binary is ready.TODO:
- Refactoringtaskutilandcontainer_ioto use customcio.Creatorfor all flags(-d,-t,-i,-a). This would unblock attach for -d.[X] Changes for windows.
[X] Adding integration tests
