Add support for autoStorageContainerName in resourceFile for Batch

[devaradhanm]

Currently Batch supports creating task (using BatchServiceClient.task.addCollection api) with resourceFile containing autoStorageContainerName in the task configuration. But the nodejs api doesnt seem to recognize autoStorageContainerName & throws error if blobSource is not passed.

The below config for resource file is supported by Batch service.

 "resourceFiles": [
                {
                    "autoStorageContainerName": "blob-container-name"
                }
            ],

But the nodejs api throws error that blobSource property is missing. Also, autoStorageContainerName property is missing in the ResourceFile interface
