Add sample data for system with Stratis, LVM and multipath block devices

Adding sample for testing with block devices.

@safchain I'm wondering if this might be helpful for testing the new UI? I think the blockdev probe is not populating the database properly. I'm not sure of the cause. Currently everything is under "Not Classified". Is there a tag I should be adding to the metadata?

Thanks for any help.

@trgill thanks for submitting this file, it will definitely help providing support for storage. In order to "classify" nodes there is nothing to do on the metadata side. There is a config file that you can use to define node attributes from metadata. https://github.com/skydive-project/skydive-ui/blob/master/src/Config.ts#L231
