*   EagerTensor now supports numpy buffer interface for tensors.
*   Add toggles `tf.enable_control_flow_v2()` and `tf.disable_control_flow_v2()`
    for enabling/disabling v2 control flow.
*   Enable v2 control flow as part of `tf.enable_v2_behavior()` and
    `TF2_BEHAVIOR=1`.
*   AutoGraph translates Python control flow into TensorFlow expressions,
    allowing users to write regular Python inside `tf.function`-decorated

### Features

This component accomplishes that in the following ways:

1. By installing a separate, very basic "CNI plugin" binary onto the node to forward low-level pod lifecycle events (CmdAdd/CmdDel/etc) from whatever node-level CNI subsystem is in use to this node agent for processing via socket.
1. By running as a node-level daemonset that:

				dstBuf, err = xioutil.ReadFile(dstFilePath)
				if err != nil && !osIsNotExist(err) {
					return res, osErrToFileErr(err)
				}
			}
		}
	}

	// Preserve all the legacy data, could be slow, but at max there can be 10,000 parts.
	currentDataPath := pathJoin(dstVolumeDir, dstPath)

	var xlMeta xlMetaV2
	var legacyPreserved bool
	var legacyEntries []string
