Mount kubelet and container runtime rootdir on LSSD

Browse Source 
When environment variable NODE_LOCAL_SSD_EPHEMERAL=true,
create a RAID 0 array on all attached SSDs to mount:

- kubelet root dir
- container runtime root dir
- pod logs dir

Those directories account for all ephemeral storage.
An array is not created when there is only one SSD.
