Docker-in-docker pod doesn't work in some k8s environments because it always assumes MTU=1500, even when k8s container network's MTU is smaller than that. This causes downloads to fail intermittently in containers that run within the internal docker. Solution: allow option to override MTU in docker helm chart & the stx tool. Also: remove explicit reference to dockerd entry point script from the helm chart because its name may change in future docker image versions. TESTS ======================================= Make sure "--mtu" is passed or omitted when starting docker daemon depending on whether STX_CONTAINER_MTU is defined.
